SpaceTime Series 28 Episode 11Ancient Water on Mars and the Birth of the Universe's LightsScientists have uncovered two sets of ancient wave ripples on Mars, revealing evidence of long-dried ponds and lakes that once existed on the Red Planet. Discovered by NASA's Curiosity rover, these ripples, formed approximately 3.7 billion years ago, indicate that shallow bodies of water were open to the Martian atmosphere, challenging previous climate models suggesting an ice-covered surface. This finding extends our understanding of the timeline for liquid water on Mars and its potential for microbial life.A Quasar's Role in Cosmic IlluminationAstronomers have detected a highly variable quasar that may have played a crucial role in turning on the lights of the universe. This quasar, observed by the NuSTAR and Chandra X-ray space telescopes, is one of the most distant objects detected and provides new insights into the growth of supermassive black holes in the early universe. Its rapid brightness fluctuations offer vital clues about the epoch of reionization, a time when the universe transitioned from darkness to light.European Space Agency's Probe 3 Mission MilestoneThe European Space Agency's Probe 3 spacecraft has successfully split into two, marking a significant step in its ambitious mission. This unique formation-flying mission aims to create artificial solar eclipses to study the Sun's corona with unprecedented precision. The two spacecraft will maintain a separation of just 150 meters, demonstrating advanced navigation and propulsion technologies essential for future space exploration.00:00 Space Time Series 28 Episode 11 for broadcast on 24 January 202500:49 Discovery of ancient wave ripples on Mars06:15 Quasar may illuminate the early universe12:30 European Space Agency's Probe 3 spacecraft successfully splits18:00 Blood vessel fingerprint in the eye may indicate stroke risk22:45 Early humans adapted to desert-like conditions26:00 Global water cycle disruptions due to climate extremes30:00 Reevaluation of the Paleo diet based on ancient human dietswww.spacetimewithstuartgary.comwww.bitesz.com

This week we talk about mergers, acquisitions, and the Shale Oil Revolution.We also discuss liquid natural gas, energy diplomacy, and political hypocrisy.Recommended Book: Eversion by Alastair ReynoldsTranscriptFor the sixth year in a row, the United States is the largest oil producer in the world.As of March 2024, it's producing an average of 12.93 million barrels of oil per day, according to the US Energy Information Administration, and it periodically pops above that average for stretches of time, like in December of last year when it managed to average just over 13.3 million barrels per day.That's an absolutely astonishing volume of oil.For context, while Saudi Arabia remains the holder of the world's most substantial spare oil capacity and was the largest oil exporter in 2023, they set aside plans to increase output to 12 million barrels a day back in January, which leaves them about a million barrels a day shy of the expansion target they set in 2020.In 2023, the US produced about 28% more oil than Russia and about 33% more than Saudi Arabia, on average.The US is becoming a huge player in oil exports, too, but it really shines if you look at not just crude oil, but also natural gas liquids and refined petroleum products. In aggregate, in 2023, the United States exported nearly the same volume of these products that both Saudi Arabia and Russia produced, not exported, which is pretty wild.As is the fact that in December of 2023, the US exported about 400 billion more cubic feet of natural gas than it imported; and it imports a lot, and it only started exporting natural gas a few years ago, so that's the figure for an industry that didn't even exist until 2016, and didn't really grow until the 2020s.The US hasn't always been this kind of force in the global oil market. It's long been a consumer of huge quantities of the stuff, but while it produced a decent amount until the late-90s, competing with Russia and trailing Saudi Arabia, though not by much, US production levels dropped substantially beginning in the early 90s, the US becoming a huge importer of fossil fuels, its production levels dipping down to something closer to those of Iran by the mid-2000s; when 9/11 happened in 2001, one of the big concerns was that the US's fundamental reliance on Middle Eastern oil would complicate its military options and hamstring its economy.That all changed, though, with what became known as the Shale Revolution, when the widespread investment in and deployment of hydraulic fracturing, or "fracking" technologies, combined with developments that allowed for horizontal drilling, opened up huge swathes of new oil-rich territories in the US and Canada, making what were previously usable, but incredibly expensive to exploit fossil fuel resources less expensive and easier to tap, and southern US states in particular saw a wave of new and expanded drilling, leading to a surge in the US's production output, and ultimately allowing the US to become the top producer in the world beginning in 2018.The degree to which this has changed things, geopolitically, cannot be overstated, in the US and globally.Stateside, petroleum prices became less tethered to the whims and political motivations of mostly Middle Eastern nations and Russia, which, working together via the OPEC+ oil cartel, were long able to threaten and coerce the US government and its allies in various ways.That remained the case for a while, even after this shale oil boom, as production and export figures weren't optimally aligned. But as this new reality has set in, the US government has been more strategic in how it has stockpiled fossil fuels resources and how it's been willing to use those stockpiles to manage price fluctuations, for itself and its allies, when warranted.This has also been important for manufacturing, shipping, and other energy-hungry aspects of the US economy, and it has stoked booms in all sorts of consumer-facing industries, alongside the deployment of power-hungry infrastructure like new power plants and data centers.Globally, this increased production has allowed the US to become a player in energy diplomacy, exporting fuel to allies that needed it because of disasters or foreign meddling, and recently, the US has taken this up a notch by bolstering Europe's energy supplies in the wake of Russia's invasion of Ukraine—an invasion that led to sanctions from the EU against Russia, those sanctions arriving more slowly than they might have otherwise arrived because of concerns that Russia's stranglehold on much of the bloc's energy resources might turn into a chokehold, hobbling their economies, military preparedness, and civilian support for the sanctions, because people would be paying extreme prices for ever-shrinking volumes of energy.In the decades leading up to that invasion, many European nations, especially Germany, completely recalibrated their economies so they could profit from Russian fuel, so the fear that those fuel supplies would dry up if they made the wrong move, supported Ukraine too ardently, was a significant concern and shaped a lot of what happened in those early days of the invasion.The US started exporting liquified natural gas to the bloc, though, which is gas that's turned into a liquid using incredibly low temperatures, which shrinks it so that it's easier and cheaper to ship. And these shipments arrived first in drips and drabs, because the infrastructure on the receiving end, to convert that chilly liquid gas back into room-temperature, full-volumed gas, needed to be installed, but once that infrastructure was in place, LNG began to arrive from the US in huge volumes, a whole new energy economy popping up essentially overnight, relative to how these things typically go, anyway. And that enabled more and sterner sanctions from the EU, of a kind that may not have been feasible, lacking that energy resource backstop.What I'd like to talk about today is another, even more recent development within the US oil industry, and what it might mean for the future of this industry.—In 2023 alone, the businesses that make up the US energy sector spent about $250 billion scooping up clients, suppliers, and rivals.A poll of energy executives in December of the same year suggested we could see another $50 billion or so invested in more acquisitions and mergers over the next two years, and in 2024, so far, as of mid-March, we've already seen APA buy Callon, Chesapeake buy Southwestern, Talos buy QuarterNorth, and Sunoco acquire NuStar; these deals all close at the tale-end of Q1 or in Q2 2024, and they were worth around $4.5, $7.4, $1.29, and $7.3 billion, respectively, so nearly $20.5 billion worth of big oil industry deals, already, and the year is just getting started, so that $50 billion figure is looking prescient.The majority of next-step deals are expected to center around the Permian Basin, which is located in western Texas, with a little bit of overflow across the border into New Mexico.This basin is the highest-producing oil field in the US, generating nearly 6 million barrels of oil and around 25 billion cubic feet of natural gas each day, as of early 2024, and this is a region of intense investment and growth; oil fields around the country are shutting down, and that increase in gas and oil production that we're seeing is mostly the consequence of more effective technologies and upgrades in the hardware and software being used by the industry.So better exploration, better tools to get to the best pockets of resources, better capturing technologies and means of shuttling what they pump from place to place—it's a full stack of better tech and systems, and that is allowing the industry to consolidate its sprawl into fewer areas, many of them in the Permian Basin, and that's thought to be part of why we're seeing so much consolidation at the moment: more investment in fewer wells and fields in a smaller portion of the country is leading to more output, and that means the bigger companies with more R&D capacity and higher-end assets will tend to have a bigger advantage than their more dispersed, smaller rivals.It's anticipated, though, that a collection of variables, including that consolidation, will actually slow the growth of the US's fossil fuel-based energy industry, at least for the next few years.Less activity from fewer business entities and fewer investments that will lead directly to higher output is expected to nudge that 12.93 million barrels a day up by maybe 120,000 or 170,000 barrels per day, rather than the previously projected 1 million barrel a day increase.That's the EIA projection, as least—some other analysts have higher expectations, in some cases double or quadruple that range, but the general consensus is that more of the oil wealth in this region being owned by larger entities that are aiming for consolidation, not growth in the sense of exploring and exploiting a bajillion new wells, will likely lead to a period of more tempered industry-wide growth, and probably a period in which these now-bigger companies will be focusing on getting all their ducks in a row, reducing redundancies and inefficiencies in their new, combined collection of assets, and possibly eyeballing other acquisition targets, as well—so that'll means more investment in efficiencies, less investment in upping those already sky-high production numbers.All of this is happening within the context of efforts, globally, to reduce humanity's reliance on and use of fossil fuels. And that's led to some strange combinations of policies and political messaging, and no shortage of claims of hypocrisy from all sides of the conversation.Case in point: even as US President Biden has celebrated US energy independence and the associated security enabled and supported by this expansion of fossil fuel production and processing, he has also flogged and signed all sorts of laws and regulations meant to reduce oil use and to increase the deployment of solar, wind, and other clean energy sources.He's also pushed hard for government investment in clean energy and related infrastructure, including things like electric vehicles and upgrades for homes, and he's not alone in this: other wealthy nations in particular have been pushing hard to emphasize and enable this transition, as all the data indicates the faster we shift away from burning fossil fuels and engaging in other emitting activities, the less destructive the impacts of human-amplified climate change will be, and the less expensive it will ultimately be to adapt to those new realities, and to stop making them worse; to fully transition to a net-zero, and then eventually, a practically non-emittive future.This seemingly bipolar stance can be disorienting, especially for those it directly impacts.And consequently, rather than making everyone happy, as both sides of the climate change, renewables conversation are getting a fair bit of what they want due to these seemingly opposing investments, it's mostly just pissing everyone off, as environmentalists, climate change activists, and everyday people who are concerned about the impacts of the changing climate that they're seeing around them, more and more each year, are irritated that the segue to a non-emittive energy future isn't happening faster, while oil, gas, and coal companies are peeved that they're being elbowed out, despite having arguably gotten the country to where it is today, provide the US economy with a substantial chunk of its overall income and wealth, and in a very real way enable modern, everyday life—even for those people who want them and their products to disappear as quickly as possible.That perception of hypocrisy is difficult to sidestep, then, because while, yes—there has been a lot of new, clean infrastructure deployed, many EV and similar companies have been invested in, and on the other side there have been all those big expansions of oil and gas infrastructure and an increase in the market for those sorts of products—these two narratives are also in diametric opposition to each other, at least in the long-term, and slow-walking a transition away from fossil fuels makes climate change worse, its impacts more devastating and longer-lasting, the worst stuff arriving faster, too, while the shift toward cleaner energy is stealing market share from those emittive energy companies, and this movement toward renewables puts a cap on fossil fuel companies' very existence, as well—some policies suggesting that they can't exist, or at least not exist at any real scale, doing the type of business they've always done, past a certain, government-mandated date.And both of these perspectives are arguably true; so those victories both sides are accumulating are often lost in the sea of concomitant victories for the perceptually opposing side, which manifest as losses for the non-victorious side.It's worth noting, too, that both sides actually have pretty good arguments, in isolation.Lacking the dominant, fossil fuel-based energy sources of today, the US military wouldn't be able to operate; it simply wouldn't be able to function, which would have all sorts of knock-on effects, until and unless all of those vehicles and missiles and other bits of hardware could be replaced with cleaner versions of the same.Lacking a full-scale replacement of every fuel-chugging car, bus, train, jet, and other piece of transportation infrastructure, the US economy would come to a halt, overnight, and that would wreak untold havoc in-country and around the world.There's a chance that certain plastic goods would disappear, too, and a gobsmackingly large portion of all things created in the modern world are made of some kind of plastic, which is a petroleum product, and the well-being of that industry is in some ways correlated with the well-being of the rest of the industry's efforts.That said, if we don't shift away from the use of these fuels and materials soon, we may lose the ability to counter some of the worst impacts of climate change, including many that are deadly, like overpowered and more regular storms and heatwaves, and others that will take out ecosystems and the creatures living in those ecosystems, permanently, changes to their conditions arriving so quickly they don't have a change to adapt.Military conflicts and economy collapses may seem quaint compared to the cost and loss of lives and treasure associated with forthcoming, more common, climate change-triggered disasters and norm-shifts.There's some indication that some Big Oil companies are making tweaks to how they do things in order to reduce the distance between their economic priorities and the priorities of folks who want them to stop pumping more fossil fuels from the ground.Top mining officials from Saudi Arabia recently announced they're building out the systems and hardware necessary to extract the more than $2.5 trillion worth of metals they're so far located in their territory, for instance, and other state-run businesses have suggested they intend to do the same: leveraging their knowledge, tools, and expertise to mine and process some of the resources that'll be most necessary (and thus, valuable) for the transition to cleaner energy.Some US-based Big Oil companies have made announcements about their own intentions in this regard, some saying they'll pull lithium from their oil wells, while others claim they're investing in rare earth mining infrastructure.ExxonMobil recently announced that it would be returning to one of its old, long-closed oil wells in a small town in Arkansas to mine lithium there, which could be beneficial for their bottom line, but also for folks in that region who were left in the lurch when Exxon left to refocus on Texas in the 1990s.A coal company operating in Wyoming, with the help of the US Department of Energy, recently discovered what could be one of the largest rare-earth metal deposits in the world, and the biggest in the US, on land that they originally bought for coal mining purposes.These sorts of investments are not consequence-free, as mining of any kind tends to deplete local resources, especially water and energy, and can have serious and deleterious effects on people and ecosystems, too. But this does seem like one of the more likely avenues through which these companies' interests may slowly come to align with those of folks, businesses, and governments that are trying to segue the US and other economies to clean energy; and that's meaningful because otherwise these companies almost always represent the most significant, well-moneyed and lobbyist-employing roadblocks to legislation and investment that would speed up the deployment of renewables and associated infrastructure; so this type of pivot would conceivably give them reason to support, rather than hamstring those efforts.That said, some of these announced efforts may end up being mostly PR plays, similar to how big oil companies have dangled the possibility of cleaning up their emissions using carbon drawdown technologies, for years, but few such investments have been made, and some of the deployed tools were eventually retired, as they didn't really do what they were supposed to do.So there are potential avenues via which priorities might align more closely in the coming years, if the economics of such paths can be worked out and if the market validates them, but there's also a chance these opposing interests remain oppositional for the foreseeable future, even though both arguably scratch necessary itches, and both represent anchors and wings for politicians who support and rely upon them.Show Noteshttps://grist.org/energy/oil-companies-used-to-run-this-town-now-theyre-back-to-mine-for-lithium/https://www.reuters.com/default/more-us-energy-deals-likely-2024-wave-consolidation-2024-01-24/https://www.semafor.com/article/03/13/2024/inside-saudi-arabias-plan-to-take-over-the-mining-industryhttps://www.reuters.com/markets/commodities/us-leads-global-oil-production-sixth-straight-year-eia-2024-03-11/https://www.reuters.com/business/energy/saudi-aramco-says-it-will-cut-planned-maximum-capacity-12-mln-bpd-2024-01-30/https://www.reuters.com/markets/commodities/record-us-oil-output-challenges-saudi-mastery-kemp-2023-12-04/https://www.visualcapitalist.com/visualizing-the-rise-of-the-u-s-as-top-crude-oil-producer/https://www.forbes.com/sites/gauravsharma/2023/12/19/as-2024-approaches-us-leads-global-crude-oil-production-roster/?sh=107f8c582706https://www.reuters.com/markets/commodities/is-us-shale-oil-revolution-over-kemp-2022-11-22/https://en.wikipedia.org/wiki/Shale_gas_in_the_United_Stateshttps://www.nrdc.org/stories/fracking-101https://www.eia.gov/dnav/ng/hist/n9133us2M.htmhttps://www.eia.gov/energyexplained/natural-gas/liquefied-natural-gas.phphttps://www.reuters.com/business/energy/us-was-top-lng-exporter-2023-hit-record-levels-2024-01-02/https://www.eia.gov/todayinenergy/detail.php?id=61523https://jpt.spe.org/the-trend-in-drilling-horizontal-wells-is-longer-faster-cheaperhttps://edition.cnn.com/2023/03/28/energy/eu-us-oil-imports-overtake-russia/index.htmlhttps://www.nytimes.com/interactive/2023/09/25/climate/fracking-oil-gas-wells-water.htmlhttps://www.newscientist.com/article/2422110-methane-leaks-from-us-oil-and-gas-are-triple-government-estimates/https://www.eia.gov/todayinenergy/detail.php?id=61523https://en.wikipedia.org/wiki/Petroleum_in_the_United_Stateshttps://www.marketplace.org/2024/02/12/diamondback-and-endeavor-merger-trend-bigger-fewer-oil-companies/https://www.strausscenter.org/energy-and-security-project/the-u-s-shale-revolution/ This is a public episode.

Hard X-ray Observations of the Hydrogen-poor Superluminous Supernova SN 2018hti with NuSTAR by Igor Andreoni et al. on Wednesday 30 November Some Hydrogen-poor superluminous supernovae are likely powered by a magnetar central engine, making their luminosity larger than common supernovae. Although a significant amount of X-ray flux is expected from the spin down of the magnetar, direct observational evidence is still to be found, giving rise to the "missing energy" problem. Here we present NuSTAR observations of nearby SN 2018hti 2.4y (rest frame) after its optical peak. We expect that, by this time, the ejecta have become optically thin for photons more energetic than about 15keV. No flux is detected at the position of the supernova down to $F_{rm{10-30keV}} = 9.0times 10^{-14}$ erg cm$^{-2}$ s$^{-1}$, or an upper limit of $7.9 times 10^{41}$ erg s$^{-1}$ at a distance of 271Mpc. This constrains the fraction of bolometric luminosity from the putative spinning down magnetar to be $f_{rm X} lesssim 36$% in the 10-30keV range in a conservative case, $f_{rm X} lesssim 11$% in an optimistic case. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2211.15749v1

Just in time for Black Hole Friday, NASA telescopes have teamed up to reveal new details about the hot air around Cygnus X-1.

Deep X-ray and radio observations of the first outburst of the young magnetar Swift J1818 0-1607 by A. Y. Ibrahim et al. on Thursday 24 November Swift J1818.0-1607 is a radio-loud magnetar with a spin period of 1.36 s and a dipolar magnetic field strength of B~3E14 G, which is very young compared to the Galactic pulsar population. We report here on the long-term X-ray monitoring campaign of this young magnetar using XMM-Newton, NuSTAR, and Swift from the activation of its first outburst in March 2020 until October 2021, as well as INTEGRAL upper limits on its hard X-ray emission. The 1-10 keV magnetar spectrum is well modeled by an absorbed blackbody with a temperature of kT_BB~1.1 keV, and apparent reduction in the radius of the emitting region from ~0.6 to ~0.2 km. We also confirm the bright diffuse X-ray emission around the source extending between ~50'' and ~110''. A timing analysis revealed large torque variability, with an average spin-down rate nudot~-2.3E-11 Hz^2 that appears to decrease in magnitude over time. We also observed Swift J1818.0-1607 with the Karl G. Jansky Very Large Array (VLA) on 2021 March 22. We detected the radio counterpart to Swift J1818.0-1607 measuring a flux density of S_v = 4.38+/-0.05 mJy at 3 GHz, and a half ring-like structure of bright diffuse radio emission located at ~90'' to the west of the magnetar. We tentatively suggest that the diffuse X-ray emission is due to a dust scattering halo and that the radio structure may be associated with the supernova remnant of this young pulsar, based on its morphology. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2211.12391v1

Deep X-ray and radio observations of the first outburst of the young magnetar Swift J1818 0-1607 by A. Y. Ibrahim et al. on Wednesday 23 November Swift J1818.0-1607 is a radio-loud magnetar with a spin period of 1.36 s and a dipolar magnetic field strength of B~3E14 G, which is very young compared to the Galactic pulsar population. We report here on the long-term X-ray monitoring campaign of this young magnetar using XMM-Newton, NuSTAR, and Swift from the activation of its first outburst in March 2020 until October 2021, as well as INTEGRAL upper limits on its hard X-ray emission. The 1-10 keV magnetar spectrum is well modeled by an absorbed blackbody with a temperature of kT_BB~1.1 keV, and apparent reduction in the radius of the emitting region from ~0.6 to ~0.2 km. We also confirm the bright diffuse X-ray emission around the source extending between ~50'' and ~110''. A timing analysis revealed large torque variability, with an average spin-down rate nudot~-2.3E-11 Hz^2 that appears to decrease in magnitude over time. We also observed Swift J1818.0-1607 with the Karl G. Jansky Very Large Array (VLA) on 2021 March 22.

The unaltered pulsar: GRO J1750-27, a super-critical X-ray neutron star that does not blink an eye by C. Malacaria et al. on Tuesday 22 November When accreting X-ray pulsars (XRPs) undergo bright X-ray outbursts, their luminosity-dependent spectral and timing features can be analysed in detail. The XRP GRO J1750-27 recently underwent one of such episodes, during which it was observed with $NuSTAR$ and monitored with $NICER$. Such a data set is rarely available, as it samples the outburst over more than a month at a luminosity that is always exceeding ${sim}5times10^{37},$erg/s. This value is larger than the typical critical luminosity value, where a radiative shock is formed above the neutron star's surface. Our data analysis of the joint spectra returns a highly ($N_Hsim(5-8)times10^{22},$cm$^{-2}$) absorbed spectrum showing a K$alpha$ iron line, a soft blackbody component likely originating from the inner edge of the accretion disk, and confirms the discovery of one of the deepest cyclotron lines, at a centroid energy of ${sim}44,$keV corresponding to a magnetic field strength of $4.7times10^{12},$G. This value is independently supported by the best-fit physical model for spectral formation in accreting XRPs which, in agreement with recent findings, favours a distance of $14$ kpc and also reflects a bulk-Comptonization dominated accretion flow. Contrary to theoretical expectations and observational evidence from other similar sources, the pulse profiles as observed by $NICER$ through the outburst raise, peak and decay remain remarkably steady. The $NICER$ spectrum, including the iron K$alpha$ line best-fit parameters, also remain almost unchanged at all probed outburst stages, similar to the pulsed fraction behaviour. We argue that all these phenomena are linked and interpret them as resulting from a saturation effect of the accretion column's emission, which occurs in the high-luminosity regime. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2211.06367v2

Spectral properties of the Be X-ray pulsar 2S 1553-542 during Type II outbursts by Binay Rai et al. on Monday 21 November We present an extended study of the Be/X-ray pulsar 2S 1553-542 during its Type II outbursts. We have incorporated emph{NICER, Swift-XRT, RXTE-PCA, emph{NuSTAR} and FERMI} observations to carry out the detailed phase and time resolved spectral analysis of the source. We have summarized the evidence of variability of the cyclotron feature observed in the X-ray continuum of the source with respect to the pulse phases of the pulsar by using the recent emph{NuSTAR} observation of 2021 outburst of the source. The time resolved spectral analysis has been performed by considering emph{RXTE} observations of the 2008 outburst of the pulsar. The hardness intensity diagram (HID) has been obtained using 2008 observations in which the intensity follows distinct branches with respect to the hardness ratio. Diagonal branch is observed in the high intensity state whereas the horizontal branch corresponds to the low intensity state. The transition from the diagonal to horizontal branch occurs at the luminosity of $(4.88pm0.24);times;10^{37};erg;s^{-1}$. The photon-index exhibits a weak positive correlation with flux along the diagonal branch and negative correlation along the horizontal branch. The existence of two different diagonal and horizontal branches further reflects the possibility of two different accretion states separated by the critical luminosity. The spin-up rate during the outburst phase is found to depend on the flux and is found to increase with an increase in flux. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2211.09082v2

A NuSTAR view of SS433: Precessional evolution of the jet-disk system by Federico A. Fogantini et al. on Tuesday 18 October SS433 is a Galactic microquasar with powerful outflows (double jet, accretion disk and winds) with well known orbital, precessional and nutational period. In this work we characterise different outflow parameters throughout the precessional cycle of the system. We analyse 10 NuSTAR ($3-70$ keV) observations of $sim$30~ks that span $sim$1.5 precessional cycles. We extract averaged spectra and model them using a combination of a double thermal jet model (bjet) and pure neutral and relativistic reflection (xillverCp and relxilllpCp) over an accretion disk. We find an average jet bulk velocity of $beta = v/c sim0.29$ with an opening angle of $lesssim$6~degrees. Eastern jet kinetic power ranges from 1 to $10^{39}$~erg/s, with base "coronal" temperatures $T_o$ ranging between 14 and 18 keV. Nickel to iron abundances remain constant at $sim$9 (within 1$sigma$). The western to eastern jet flux ratio becomes $sim1$ on intermediate phases, about 35% of the total precessional orbit. The $3-70$ keV total unabsorbed luminosity of the jet and disk ranges from 2 to 20 $times$10$^{37}$~erg/s, with the disk reflection component contributing mainly to the hard $20-30$ keV excess and the stationary 6.7 keV ionized Fe line complex. At low opening angles $Theta$ we find that the jet expands sideways following an adiabatic expansion of a gas with temperature $T_o$. Finally, the central source and lower parts of the jet could be hidden by an optically thick region of $tau > 0.1$ and size $Rsim N_H/n_{e0}sim1.5times10^9$~cm$sim$1700~$r_g$ for $M_{BH}=3~M_{odot}$ arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2210.09390v1

Broadband X-ray Spectral Analysis of the Dual AGN System Mrk 739 by Koki Inaba et al. on Monday 17 October We present the result of a broadband (0.5-70 keV) X-ray spectral analysis of the late-merger galaxy Mrk 739, which contains a dual active galactic nucleus (AGN), Mrk 739E and Mrk 739W, with a separation of $sim$3.4 kpc. The spectra obtained with NuSTAR, Chandra, XMM-Newton and Swift/BAT are simultaneously analyzed by separating the contributions from the two AGNs and extended emission with the Chandra data. To evaluate the reflection components from the AGN tori, we consider two models, a phenomenological one (pexrav and zgauss) and a more physically motivated one (XCLUMPY; Tanimoto et al. 2019). On the basis of the results with XCLUMPY, we find that the AGNs in Mrk 739E and Mrk 739W have intrinsic 2-10 keV luminosities of $1.0 times 10^{43}$ and $7.5 times 10^{41} rm{erg} rm{s}^{-1}$ absorbed by hydrogen column densities of $N_{rm{H}} < 6.5 times 10^{19} rm{cm}^{-2}$ and $N_{rm{H}} = 6.9^{+3.2}_{-1.7} times 10^{21} rm{cm}^{-2}$, respectively. The torus covering fraction of the material with $N_{rm{H}} > 10^{22} rm{cm}^{-2}$ in Mrk 739E, $C_{rm{T}}^{(22)} < 0.50$ at a 90% confidence limit, is found to be smaller than those found for late-merger ultra/luminous infrared galaxies, $C_{rm{T}}^{(22)} = 0.71pm0.16$ (mean and standard deviation; Yamada et al. 2021). Considering the small star formation rate of Mrk 739E, we suggest that the gas-to-mass ratio of the host galaxy is an important parameter to determine the circumnuclear environment of an AGN in late merger. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2210.08791v1

Spectral characteristics of the black hole binary 4U 1957+115: A multi-mission perspective by Sneha Prakash Mudambi et al. on Wednesday 12 October We report spectral analysis of the persistent black hole X-ray binary, 4U 1957+115, using AstroSat, Swift and NuSTAR observations carried out between 2016-2019. Modelling with a disk emission, thermal comptonization and blurred reflection components revealed that the source was in the high soft state with the disk flux $sim 87$ % of the total and high energy photon index $sim2.6$. There is an evidence that either the inner disk radius varied by $sim25$ % or the colour hardening factor changed by $sim12$ %. The values of the inner disk radius imply that for a non-spinning black hole, the black hole mass is $30 $ kpc away. On the other hand, a rapidly spinning black hole would be consistent with the more plausible black hole mass of $< 10$ M$_odot$ and a source distance of $sim10$ kpc. Fixing the distance to $10$ kpc and using a relativistic accretion disk model, constrained the black hole mass to 6 M$_odot$ and inclination angle to 72$^{circ}$. A positive correlation is detected between the accretion rate and inner radii or equivalently between the accretion rate and colour factor. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2210.05606v1

Multi-wavelength observations of the obscuring wind in the radio-quiet quasar MR 2251-178 by Junjie Mao et al. on Wednesday 12 October Obscuring winds driven away from active supermassive black holes are rarely seen due to their transient nature. They have been observed with multi-wavelength observations in a few Seyfert 1 galaxies and one broad absorption line radio-quiet quasar so far. An X-ray obscuration event in MR 2251-178 was caught in late 2020, which triggered multi-wavelength (NIR to X-ray) observations targeting this radio-quiet quasar. In the X-ray band, the obscurer leads to a flux drop in the soft X-ray band from late 2020 to early 2021. X-ray obscuration events might have a quasi-period of two decades considering earlier events in 1980 and 1996. In the UV band, a forest of weak blueshifted absorption features emerged in the blue wing of Ly$alpha$ $lambda1216$ in late 2020. Our XMM-Newton, NuSTAR, and HST/COS observations are obtained simultaneously, hence, the transient X-ray obscuration event is expected to account for the UV outflow, although they are not necessarily caused by the same part of the wind. Both blueshifted and redshifted absorption features were found for He {sc i} $lambda10830$, but no previous NIR spectra are available for comparison. The X-ray observational features of MR 2251-178 shared similarities with some other type 1 AGNs with obscuring wind. However, observational features in the UV to NIR bands are distinctly different from those seen in other AGN with obscuring winds. A general understanding of the observational variety and the nature of obscuring wind is still lacking. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2210.05939v1

NuSTAR observation of X-ray pulsar 1E 1145 1-6141 by Manoj Ghising et al. on Tuesday 11 October In this paper, we report on the hard X-ray observation of the X-ray pulsar 1E 1145.1-6141 performed with the Nuclear Spectroscopic Telescope Array mission (NuSTAR). The coherent pulsation of the source with a period of $sim296.653;pm;0.021;s $ is detected. The source may be in the equilibrium phase, according to the most recent measurements of its pulse period. The pulse profile reveals a mild energy dependence and generally hints at a pencil-beam pattern. The pulse profile have evolved with time. The Pulse fraction is found to depend on energy with a fall in the value at $sim 32; keV$. The NuSTAR spectra can be approximated by a composite model with two continuum components, a blackbody emission, cut-off powerlaw, and a discrete component in the form of gaussian to account for the emission line of iron. The estimated absorbed flux of the source is $sim6times10^{-10};erg;cm^{-2};s^{-1}$ which corresponds to a luminosity of $sim5times 10^{36};erg;s^{-1}$. Pulse phase-resolved spectroscopy were performed to understand the evolution of spectral parameters with pulse phase. The estimated blackbody radius is found to be consistent with the size of the theoretical prediction. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2210.05163v1

Modeling the time variable spectral energy distribution of the blazar CTA 102 from 2008 to 2022 by N. Sahakyan et al. on Monday 10 October We present long-term multiwavelength observations of blazar CTA 102 ($z=1.037$). Detailed temporal and spectral analyses of $gamma$-ray, X-ray and UV/optical data observed by {it Fermi}-LAT, Swift XRT, NuSTAR and Swift-UVOT over a period of 14 years, between August 2008 and March 2022, was performed. We found strong variability of source emission in all the considered bands, especially in the $gamma$-ray band it exhibited extreme outbursts when the flux crossed the level of $10^{-5}:{rm photon:cm^{-2}:s^{-1}}$. Using the Bayesian Blocks algorithm, we split the adaptively binned $gamma$-ray light curve into 347 intervals of quiescent and flaring episodes and for each period built corresponding multiwavelength spectral energy distributions (SEDs), using the available data. Among the considered SEDs, 117 high-quality (quasi) contemporaneous SEDs which have sufficient multiwavelength data, were modeled using JetSeT framework within a one-zone leptonic synchrotron and inverse Compton emission scenario assuming the emitting region is within the broad-line-region and considering internal and external seed photons for the inverse Compton up-scattering. As a result of modeling, the characteristics of the relativistic electron distribution in the jet as well as jet properties are retrieved and their variation in time is investigated. The applied model can adequately explain the assembled SEDs and the modelling shows that the data in the bright flaring periods can be reproduced for high Doppler boosting and magnetic field. The obtained results are discussed in the context of particle cooling in the emitting region. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2210.04663v1

NuSTAR observations of a heavily X-ray obscured AGN in the dwarf galaxy J144013+024744 by Shrey. Ansh et al. on Wednesday 21 September We present a multi-wavelength analysis of the dwarf Seyfert-2 galaxy J$144013+024744$, a candidate obscured active galactic nucleus (AGN) thought to be powered by an intermediate-mass black hole (IMBH, $M_bullet approx 10^{4-6} M_odot$) of mass $M_{bullet} sim 10^{5.2}M_odot$. To study its X-ray properties, we targeted J$144013+024744$ with NuSTAR for $approx 100$ ks. The X-ray spectrum was fitted with absorbed power law, Pexmon and a physical model (RXTorus). A Bayesian X-ray analysis was performed to estimate the posteriors. The phenomenological and the physical models suggest the AGN to be heavily obscured by a column density of $N_{rm H} = (3.4-7.0)times10^{23}$ cm$^{-2}$. In particular, the RXTorus model with a sub-solar metallicity suggests the obscuring column to be almost Compton-thick. We compared the $2-10$ keV intrinsic X-ray luminosity with the inferred X-ray luminosities based on empirical scaling relations for unobscured AGNs using $L_{rm [OIV](25.89mu {rm m})}$, $L_{[{rm OIII}](5007 {rm angstrom})}$, and $L_{6rm mu m}$ and found that the high-excitation $[{rm OIV}]$ line provides a better estimate of the intrinsic $2-10$ keV X-ray luminosity ($L_{2-10}^{rm int} sim 10^{41.41}{rm erg s}^{-1}$). Our results suggest that J$144013+024744$ is the first type-2 dwarf galaxy that shows X-ray spectroscopic evidence for obscuration. The column density that we estimated is among the highest measured to date for IMBH-powered AGNs, implying that a typical AGN torus geometry might extend to the low-mass end. This work has implications for constraining the black hole occupation fraction in dwarf galaxies using X-ray observations. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2209.09913v1

X-ray spectral and timing analysis of the Compton Thick Seyfert 2 galaxy NGC 1068 by Indrani Pal et al. on Wednesday 21 September We present the timing and spectral analysis of the Compton Thick Seyfert 2 active galactic nuclei NGC 1068 observed using {it NuSTAR} and {it XMM-Newton}. In this work for the first time we calculated the coronal temperature ($rm{kT_{e}}$) of the source and checked for its variation between the epochs if any. The data analysed in this work comprised of (a) eight epochs of observations with {it NuSTAR} carried out during the period December 2012 to November 2017, and, (b) six epochs of observations with {it XMM-Newton} carried out during July 2000 to February 2015. From timing analysis of the {it NuSTAR} observations, we found the source not to show any variations in the soft band. However, on examination of the flux at energies beyond 20 keV, during August 2014 and August 2017 the source was brighter by about 20% and 30% respectively compared to the mean flux of the three 2012 {it NuSTAR} observations as in agreement with earlier results in literature. From an analysis of {it XMM-Newton} data we found no variation in the hard band (2 $-$ 4 keV) between epochs as well as within epochs. In the soft band (0.2 $-$ 2 keV), while the source was found to be not variable within epochs, it was found to be brighter in epoch B relative to epoch A. By fitting physical models we determined $rm{kT_{e}}$ to range between 8.46$^{+0.39}_{-0.66}$ keV and 9.13$^{+0.63}_{-0.98}$ keV. From our analysis, we conclude that we found no variation of $rm{kT_{e}}$ in the source. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2209.10261v1

X-ray Absorption and Reprocessing in the z sim 2 5 Lensed Quasar 2MASS J1042+1641 by D. J. Walton et al. on Thursday 08 September We present new broadband X-ray observations of the $z sim 2.5$ lensed quasar 2MASS J1042+1641, combining $XMM$-$Newton$, $Chandra$ and $NuSTAR$ to provide coverage of the X-ray spectrum over the 0.3$-$40 keV bandpass in the observed frame, corresponding to the $sim$1$-$140 keV band in the rest-frame of 2MASS J1042+1641. The X-ray data show clear evidence for strong (but still Compton-thin) X-ray absorption, $N_{rm{H}} sim 3-4 times 10^{23}$ cm$^{-2}$, in addition to significant reprocessing by Compton-thick material that must lie away from our line-of-sight to the central X-ray source. We test two different interpretations for the latter: first that the reprocessing occurs in a classic AGN torus, as invoked in unification models, and second that the reprocessing occurs in the accretion disc. Both models can successfully reproduce the observed spectra, and both imply that the source is viewed at moderately low inclinations ($i < 50^{circ}$) despite the heavy line-of-sight absorption. Combining the X-ray data with infrared data from $WISE$, the results seen from 2MASS J1042+1641 further support the recent suggestion that large X-ray and IR surveys may together be able to identify good lensed quasar candidates in advance of detailed imaging studies. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2209.03381v1

Jet-ISM interaction in NGC 1167 B2 0258+35, A LINER with an AGN past by G. Fabbiano et al. on Wednesday 07 September We report the results of joint Chandra/ACIS - NuSTAR deep observations of NGC 1167, the host galaxy of the young radio jet B2 0258+35. In the ACIS data we detect X-ray emission, extended both along and orthogonal to the jet. At the end of the SE radio jet, we find lower-energy X-ray emission that coincides with a region of CO turbulence and fast outflow motions. This suggests that the hot Interstellar Medium (ISM) may be compressed by the jet and molecular outflow, resulting in more efficient cooling. Hydrodynamic simulations of jet-ISM interaction tailored to NGC 1167 are in agreement with this conclusion and with the overall morphology and spectra of the X-ray emission. The faint hard nuclear source detected with Chandra and the stringent NuSTAR upper limits on the harder X-ray emission show that the active galactic nucleus (AGN) in NGC 1167 is in a very low-accretion state. However, the characteristics of the extended X-ray emission are more consonant to those of luminous Compton Thick AGNs, suggesting that we may be observing the remnants of a past high accretion rate episode, with sustained strong activity lasting ~ 2 x 103 yr. We conclude that NGC1167 is presently a LINER, but was an AGN in the past, given the properties of the extended X-ray emission and their similarity with those of CT AGN extended emission. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2209.02549v1

Spectral variability in NGC 1042 ULX1 by Tanuman Ghosh et al. on Tuesday 06 September We report X-ray spectral variability in an ultraluminous X-ray source NGC 1042 ULX1, using archival XMM-NEWTON and recent NuSTAR observations. In long-term evolution, the source has shown a trend of variation in spectral hardness. The variability in different XMM-NEWTON observations is prominent above $sim 1$ keV. Cool thermal disk component with a characteristic temperature of $sim 0.2$ keV manifests that the spectral state of NGC 1042 ULX1 in all epochs is similar to that of the ultraluminous state sources. An apparent anti-correlation between luminosity and powerlaw index demonstrates that the source becomes spectrally harder when it is in a brighter state. That is conceivably related to stronger Comptonization when the accretion rate is higher or due to a change in the occultation of the disk geometry. Typical hard ultraluminous type spectra indicate that NGC 1042 ULX1 is a low inclination system in general. Spectral properties suggest that, like many other ULXs which show spectral curvature around $sim 6-10$ keV, NGC 1042 ULX1 could be another stellar-mass super-Eddington accretor. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2209.02458v1

Modern astronomical cameras capture data in a format called a FITS (Flexible Image Transport System) file. FITS files cannot be opened by many common image processing programs. FITS Liberator 4 is a program that opens FITS files and saves them in a format the can be opened and manipulated by common image processing programs.    In this podcast, Robert Hurt (IPAC) talks about FITS files, the history of FITS Liberator, how you can use FITS Liberator 4 to create your own images and some sources of astronomical data.   Robert Hurt is an astronomer and visualization scientist working at IPAC, a science and data center for astrophysics and planetary science at Caltech. His primary work has been for NASA's Spitzer Space Telescope, but a variety of other communications projects have spanned many other NASA missions across the spectrum including Kepler, WISE/NEOWISE, NuSTAR, GALEX, as well as other Caltech projects like LIGO. ​ While his principle interests have been in the visual side of science communications, he has also been involved with many other aspects of the science visualization community including the development of metadata standards for astrophysics outreach, including the AstroPix image site. He has also produced various video projects and podcasts spanning many topics in astronomy.   Bio: Rob Sparks is in the Communications, Education and Engagement group at NSF's NOIRLab.   Links: FITS Liberator 4 annoucement: https://noirlab.edu/public/blog/noirlab-pretty-pictures/ FITS Liberator 4 download: https://noirlab.edu/public/products/fitsliberator/ Coloring the Universe podcast: https://cosmoquest.org/x/365daysofastronomy/2015/12/12/dec-12th-coloring-the-universe/ MAST Archives at Space Telescope Science Institute: https://archive.stsci.edu/ NASA/IPAC Infrared Science Archive: https://irsa.ipac.caltech.edu/frontpage/ NOIRLab social media channels can be found at: https://www.facebook.com/NOIRLabAstro https://twitter.com/NOIRLabAstro https://www.instagram.com/noirlabastro/ https://www.youtube.com/noirlabastro   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!

Ana Guzman, ideaXme space ambassador and leading space communications and space exploration television producer interviews Caley Burke, Aerospace Engineer and Trajectory Analyst for NASA's Launch Program. Ana Guzman comments: In my next interview for ideaXme, I was able to sit down and chat with Caley Burke, aerospace engineer at NASA’s Launch Services Program. She works on the interface between the spacecraft and launch vehicle teams to get the spacecraft delivered to their final destination in space. As part of her work, she analyzes trajectories of the rockets launching NASA and NOAA robotic spacecraft missions. Reducing Risk During Delivery of NASA's Exploratory Missions: Her position contributes to space exploration by providing expertise in reducing risk during the delivery of NASA exploratory missions to space and maintaining a wealth of knowledge in the expendable launch vehicle market. We discuss factors taken into account when deciding which trajectories and rockets are chosen for each mission, launch windows and opportunities from different parts of the world, and why a launch window to Mars occurs only every two years. Caley worked on the launches of Mars Science Laboratory (MSL) and the Mars 2018 lander, InSight, on an Atlas V, NuSTAR on a Pegasus XL, and Soil Moisture Active Passive (SMAP) on a Delta II. She did early work on the Joint Polar Satellite System 2 (JPSS-2) mission to launch on an Atlas V rocket. NASA Kennedy Space Center: She started her NASA career as a Pathways intern in 2002 at Kennedy Space Center with the International Space Station (ISS) and later transferred to the Launch Services Program in 2003. She attended MIT (Massachusetts Institute of Technology) via the Kennedy Graduate Fellowship Program and performed fluid slosh in microgravity research on the Synchronized Position Hold Engage and Reorient Experimental Satellites (SPHERES) platform on the ISS.

La galaxie du Feu d'Artifice (alias NGC 6946) a encore frappé ! Cette galaxie célèbre pour sa richesse en supernovas était observée avec le télescope spatial NuSTAR associé à XMM-Newton pour étudier ses sources X ultra-lumineuses, lorsqu'une nouvelle source X inconnue est apparue non loin du centre de la galaxie, puis a disparu aussi vite qu'elle était apparue. Elle pourrait avoir plusieurs origines... Une étude parue dans The Astrophysical Journal.

Audra Fahey, the Vice President of Tax with publicly-traded NuStar Energy, was our guest for this episode of Life In Accounting, a podcast production of Where Accountants Go. It Was Meant To Be… One of the interesting points that came out early in the interview was that Audra was hired right out of school to be an auditor actually. As luck would have it though, she also was offered an internship in tax with the same firm for her last semester in college.  After she graduated, the firm had a need in the tax department and she had enjoyed it, so she ended up starting on the tax side instead.  It was a fortunate turn of events. With Accounting You Can Work Anywhere With her husband being in the military, they were transferred to San Antonio. One of the reasons she had decided to pursue accounting as a career in the first place was that you could work literally anywhere, and that decision paid off with this relocation.  Audra was very quickly hired at KPMG and stayed with them over a decade. Transitioning to Industry… As her position became more and more involved with Sarbanes Oxley work, she decided it was time to transition out into industry. She joined Valero Energy, but in the division that was spun off only a few months later into the newly-formed NuStar Energy, another NYSE-traded company.  It was the opportunity of a lifetime, as she got the chance to build the tax function from the ground-up with NuStar.  Now in her role as Vice President of Tax, she oversees all tax functions including international tax, with the exception of property and payroll taxes, and has a team of 16 highly-qualified professionals. And we haven't even gotten to the part where she began teaching a Master's level tax course at a local university!

Selon des nouvelles données obtenues avec le télescope spatial NuSTAR, l'étoile binaire ultramassive Eta Carinae accélère des particules jusqu'à des hautes énergies, se révélant ainsi être une nouvelle source de rayons cosmiques pouvant arriver au niveau de la Terre située à seulement 7500 années-lumière de distance.

Dr. Lisa Storrie-Lombardi returns to the show to discuss NuSTAR, Spitzer, and what it feels like to end a mission you’ve been working on for decades. Cassini’s Grand Finale has us reflecting on the upcoming demise of the Spitzer Space Telescope.

Lisa Trefger, CPA and recently the Director of Business Analytics for Nustar, joined us for this week's episode of Life In Accounting: The Where Accountants Go podcast. “Where all the fun happens” I invited Lisa on the show for several reasons, one of which was to discuss the field of business analytics in the accounting profession. I think the quote above from Lisa says it all… business analytics is a certainly a technical field, but also a very interesting field in that the numbers tell you a story of what the true drivers are for an organization. It's a field that Lisa really enjoys and feels blessed to work in. Qualifications Although we discuss many aspects of Lisa's career on the podcast naturally, I definitely wanted to get into how one may be able to prepare to move into analytics for those that may want to direct their career that way. According to Lisa there are obviously many good paths that can get you there, but a role where you get to see the ‘big picture' such as in public accounting is very beneficial, as well as becoming a power-user of Excel. Given that the roles are focused on data analysis, getting an MBA can also go a long way to prepare an individual from an educational standpoint. Community Involvement I knew going into the interview that Lisa donated some of her time to helping the nonprofit community, but I had no idea how involved she was. She credits Nustar with giving her that flexibility to be able to spend time in the community, but obviously she has been proactive about getting involved. Some of the organizations she mentions are Dress for Success & Career Gear – https://sanantonio.dressforsuccess.org/ Women's Energy Network – https://www.womensenergynetwork.org/ 100 Women Who Care   She also makes a book recommendation towards the end – “The Go Giver” by Bob Burg. I hope you enjoy this episode as much as I did when recording it. Lisa really was a pleasure to interview. Have a great week!

Une équipe d'astronomes utilisant le télescope spatial NuSTAR, montre en étudiant 52 galaxies à noyau actif à différents stades de fusions galactiques que celles qui en sont au dernier stade ont un trou noir supermassif complètement enveloppé par un épais cocon sphérique de gaz.

La source de rayons X qui domine toute la galaxie d'Andromède vient d'être identifiée, il s'agirait d'un seul et unique pulsar, nommé Swift J0042.6+4112. Cette mise en évidence a été effectuée avec le télescope spatial NuSTAR.

Le télescope spatial NuSTAR vient de permettre de visualiser pour la première fois la structure du disque de matière entourant un trou noir supermassif, et contrairement à l'image ordonnée et lisse que se faisaient les astrophysiciens jusqu'alors, ce disque apparaît très désordonné...

NuStar Energy - The Millennial Career Playbook

ASTRO-H : sous ce nom qui évoque un dessin animé japonais, se cache l'un des plus beaux outils des astrophysiciens. ASTRO-H est un télescope spatial de nouvelle génération, spécialisé dans l'observation des rayons X. Il va compléter, voire supplanter, dès l'année prochaine les trois principaux télescopes à rayons X en activité que sont les américains Chandra et NUSTAR et l'européen XMM-Newton.

"Waouh, qu'est ce que c'est que ce truc ?". C'est certainement ce que se sont dit les astrophysiciens exploitant le télescope spatial NuSTAR, spécialisé dans la détection des rayons X. Ce truc s'avère être un pulsar, mais extrêmement puissant, pour ne pas dire extrêmement extrême... C'est bien une étoile à neutron en rotation qui pulse des rayonnements, mais elle produit autant d'énergie qu'un très gros trou noir, autant d'énergie que 10 millions de soleils, excusez du peu.

Dead men tell no tales, but dead stars have plenty to say. Traces of elements left behind after stars explode can inform astronomers about how the star was ripped apart. NuSTAR, the first telescope capable of detecting high-energy X-ray signatures of radioactive elements in supernova remnants, recently captured a picture of a dying star’s last gasp.

It's an exciting experience for any space geek to watch a new satellite launch into orbit. Earlier in 2012, we were excited about the launch of NuSTAR, a small explorer X-ray mission collaboratively created by teams at Caltech, NASA, and over a dozen other institutions around the world. NuSTAR advances the international astronomical community's ability to observe some of the hottest, densest, and most energetic objects in the Universe. We were interested to find out more about NASA Goddard's involvement in the mission, so we interviewed post-doc Dr. Dan Wik about his work with the satellite's optics and his interest in observing galaxy clusters with NuSTAR.

Black holes have been the stuff of science fiction since their discovery in the late sixties. But now a new, nimble NASA telescope is using its powerful x-ray vision to hunt for these abundant yet invisible, massive space oddities.

Astronomer har også brug for røntgen, ligesom tandlæger, lufthavnens sikkerhedsfolk og læger på hospitalerne. Astronomerne kan bruge røntgen til at se så forskellige objekter som solen, sorte huller og fjerne galakser. Foredraget handler om en ny avanceret teknologi fra DTU Space, som skal anvendes i NASA’s videnskabelige satellit ’NuSTAR’, der sendes i rummet i 2012. Tidligere har astronomerne haft mulighed for at lave teleskoper, der kan fokusere strålingen fra den såkaldt bløde del af røntgenstrålingen, men den hårde stråling har man endnu ikke kunnet fokusere. Nu kan et fokuserende teleskop med hundrede gange større følsomhed end tidligere opnået i den hårde ende af røntgenspektret for første gang nogensinde sætte astronomer i stand til at detektere sorte huller og andre kompakte objekter i vores egen galakse mælkevejen og i fjerne galakser.
