If a black hole shreds a star and nobody is around to hear it, does it make a sound? To find out, Dr. Charles Liu and co-host Allen Liu welcome Professor Yvette Cendes, (aka u/Andromeda321 on Reddit), a Radio Astronomer studying transient radio signals from space. As always, though, we start off with the day's joyfully cool cosmic thing, a report by the Dark Energy Survey that seems to show that the amount of dark energy originally described as the cosmological constant by Albert Einstein might in fact be variable. As Prof. Cendes explains, the data indicates that universal expansion is still accelerating but the rate might be changing. After Yvette explains what she does, and how radio astronomy works in concert with optical astronomy to deliver a more complete understanding, Chuck asks her to explain Tidal Disruption Events, or TDEs, about which she's a world expert. A TDE is when a star wanders too close to a supermassive black hole and ends up getting shredded. Yvette prefers to call them “Shredders.” Our first audience question comes from Nachama, who asks, “When will the black hole in the Milky Way eat the Sun?” The good news, according to Yvette, is that will never happen. As she explains, black holes actually don't suck any more than anything that massive would, and we're 25-30,000 light years away from Sagittarius A* – too far away to worry about. Next, Chuck asks Yvette about one of the most famous transient signals we've ever found, the so called “Wow!” signal detected in 1977 by Jerry Ehman at the now-defunct Xavier Observatory in Ohio. Because the signal looked exactly like what might be expected if it were of extraterrestrial origin, Ehman circled it on the printout and wrote, “Wow!” Unfortunately, it never repeated. The most likely explanation, according to Dr. Cendes, is that it was some sort of manmade interference, although the signal is currently being reinvestigated. Yvette recounts how she ended up ended up as a first-term professor at the University of Oregon after studying in the Netherlands and Toronto and working at Harvard. Then she answers an audience question from Yan Min, who asks, “Where is the best place in the world to study astronomy? I live in New York – Is it New York?” Unfortunately for Yankees fans, Yvette says it would most likely be Cambridge, Massachusetts thanks to Harvard, which has the biggest number of astronomers under one roof and operates the Chandra X-Ray Observatory, and M.I.T. on the other side of town if you get bored. Chuck asks Yvette what happens after a black hole shreds a star. Shredders, she explains, are rare. In our own Milky Way, they probably happen once every million years. Once a TDE is classified by optical astronomers, Yvette and her team point their radio telescopes at the tidal radius outside of the event horizon to discern the outflows weeks, months and even years after the initial event. He also asks Yvette if she has any hobbies to help her decompress from thinking about violent events in the universe. She likes to cross stitch, the “original pixel art.” Yvette shows us a cross stitch she made of the James Webb Space Telescope complex mirror, another featuring an 8-bit Mario screen with the words “What doesn't kill me makes me smaller,” and a third with objects in the Solar System. She also embroiders and shows us a hoop featuring the constellations visible in the northern hemisphere night sky. We end with Yvette and Allen schooling Chuck about Reddit's immense reach and value in scientific discourse. One subreddit, called r/Space, has “27 million intelligent lifeforms” subscribed to it. On Reddit, Yvette's username is u/Andromeda321, and she's one of the top users on the platform over 1 million karma points. She's known for starting her posts that explain or comment on recent discoveries with the phrase, “Astronomer here!” If you'd like to follow Dr. Yvette Cendes, you can find her on Reddit, where she's u/Andromeda321, and her dedicated subreddit, reddit.com/r/Andromeda321.

L'univers s'expand de plus en plus rapidement et pas moyen d'expliquer pourquoi. La seule solution que nous avons pu trouver jusqu'à présent est de considérer une nouvelle forme d'énergie, inconnue et invisible appelée : L'énergie noire. Cette forme d'énergie remplissant tout l'univers à près de 70%. C'est elle qui expliquerait pourquoi l'univers s'étend de plus en plus rapidement. Mais comment avons-nous découvert cette énergie ? Quelle est sa véritable nature ? Comment pensons-nous l'étudier ? Je suis parti au Chili à l'observatoire de Cerro Tololo qui a mené le projet Dark Energy Survey avec la DECam entre 2012 et 2019 pour chercher des réponses. Un autre projet est également en cours de développement : Le télescope Vera Rubin, et on en parle aussi !

From February 14th, 2024. Every time I get the digital “why can't you scientists just look at the data” lecture, I wonder what people think scientists do. All we do is look at data, and when that data tells us our understanding of the universe is wrong, we're pretty good at accepting the data and throwing out our false understandings… even when the data makes our life a whole lot harder. Such is the case with the accelerating rate of expansion of the Universe... We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.

The Dark Energy Survey Year 3 high redshift sample: Selection, characterization and analysis of galaxy clustering by C. Sánchez et al. on Wednesday 30 November The fiducial cosmological analyses of imaging galaxy surveys like the Dark Energy Survey (DES) typically probe the Universe at redshifts $z < 1$. This is mainly because of the limited depth of these surveys, and also because such analyses rely heavily on galaxy lensing, which is more efficient at low redshifts. In this work we present the selection and characterization of high-redshift galaxy samples using DES Year 3 data, and the analysis of their galaxy clustering measurements. In particular, we use galaxies that are fainter than those used in the previous DES Year 3 analyses and a Bayesian redshift scheme to define three tomographic bins with mean redshifts around $z sim 0.9$, $1.2$ and $1.5$, which significantly extend the redshift coverage of the fiducial DES Year 3 analysis. These samples contain a total of about 9 million galaxies, and their galaxy density is more than 2 times higher than those in the DES Year 3 fiducial case. We characterize the redshift uncertainties of the samples, including the usage of various spectroscopic and high-quality redshift samples, and we develop a machine-learning method to correct for correlations between galaxy density and survey observing conditions. The analysis of galaxy clustering measurements, with a total signal-to-noise $S/N sim 70$ after scale cuts, yields robust cosmological constraints on a combination of the fraction of matter in the Universe $Omega_m$ and the Hubble parameter $h$, $Omega_m = 0.195^{+0.023}_{-0.018}$, and 2-3% measurements of the amplitude of the galaxy clustering signals, probing galaxy bias and the amplitude of matter fluctuations, $b sigma_8$. A companion paper $textit{(in preparation)}$ will present the cross-correlations of these high-$z$ samples with CMB lensing from Planck and SPT, and the cosmological analysis of those measurements in combination with the galaxy clustering presented in this work. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2211.16593v1

Marginal Bayesian Statistics Using Masked Autoregressive Flows and Kernel Density Estimators with Examples in Cosmology by Harry Bevins et al. on Monday 28 November Cosmological experiments often employ Bayesian workflows to derive constraints on cosmological and astrophysical parameters from their data. It has been shown that these constraints can be combined across different probes such as Planck and the Dark Energy Survey and that this can be a valuable exercise to improve our understanding of the universe and quantify tension between multiple experiments. However, these experiments are typically plagued by differing systematics, instrumental effects and contaminating signals, which we collectively refer to as `nuisance' components, that have to be modelled alongside target signals of interest. This leads to high dimensional parameter spaces, especially when combining data sets, with > 20 dimensions of which only around 5 correspond to key physical quantities. We present a means by which to combine constraints from different data sets in a computationally efficient manner by generating rapid, reusable and reliable marginal probability density estimators, giving us access to nuisance-free likelihoods. This is possible through the unique combination of nested sampling, which gives us access to Bayesian evidences, and the marginal Bayesian statistics code MARGARINE. Our method is lossless in the signal parameters, resulting in the same posterior distributions as would be found from a full nested sampling run over all nuisance parameters, and typically quicker than evaluating full likelihoods. We demonstrate our approach by applying it to the combination of posteriors from the Dark Energy Survey and Planck. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2207.11457v3

Photometric Properties of Jupiter Trojans detected by the Dark Energy Survey by DES Collobration et al. on Tuesday 22 November The Jupiter Trojans are a large group of asteroids that are co-orbiting with Jupiter near its L4 and L5 Lagrange points. The study of Jupiter Trojans is crucial for testing different models of planet formation that are directly related to our understanding of solar system evolution. In this work, we select known Jupiter Trojans listed by the Minor Planet Center (MPC) from the full six years dataset (Y6) of the Dark Energy Survey (DES) to analyze their photometric properties. The DES data allow us to study Jupiter Trojans with a fainter magnitude limit than previous studies in a homogeneous survey with $griz$ band measurements. We extract a final catalog of 573 unique Jupiter Trojans. Our sample include 547 asteroids belonging to L5. This is one of the largest analyzed samples for this group. By comparing with the data reported by other surveys we found that the color distribution of L5 Trojans is similar to that of L4 Trojans. We find that L5 Trojans' $g - i$ and $g - r$ colors become less red with fainter absolute magnitudes, a trend also seen in L4 Trojans. Both the L4 and L5 clouds consistently show such a color-size correlation over an absolute magnitude range $11 < H < 18$. We also use DES colors to perform taxonomic classifications. C and P-type asteroids outnumber D-type asteroids in the L5 Trojans DES sample, which have diameters in the 5 - 20 km range. This is consistent with the color-size correlation. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2211.10719v1

C and P-type asteroids outnumber D-type asteroids in the L5 Trojans DES sample, which have diameters in the 5 - 20 km range. This is consistent with the color-size correlation. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2211.10719v1
Photometric Properties of Jupiter Trojans detected by the Dark Energy Survey by DES Collobration et al. on Monday 21 November The Jupiter Trojans are a large group of asteroids that are co-orbiting with Jupiter near its L4 and L5 Lagrange points. The study of Jupiter Trojans is crucial for testing different models of planet formation that are directly related to our understanding of solar system evolution. In this work, we select known Jupiter Trojans listed by the Minor Planet Center (MPC) from the full six years dataset (Y6) of the Dark Energy Survey (DES) to analyze their photometric properties. The DES data allow us to study Jupiter Trojans with a fainter magnitude limit than previous studies in a homogeneous survey with $griz$ band measurements. We extract a final catalog of 573 unique Jupiter Trojans. Our sample include 547 asteroids belonging to L5. This is one of the largest analyzed samples for this group. By comparing with the data reported by other surveys we found that the color distribution of L5 Trojans is similar to that of L4 Trojans. We find that L5 Trojans' $g - i$ and $g - r$ colors become less red with fainter absolute magnitudes, a trend also seen in L4 Trojans. Both the L4 and L5 clouds consistently show such a color-size correlation over an absolute magnitude range $11 < H < 18$. We also use DES colors to perform taxonomic classifications. C and P-type asteroids outnumber D-type asteroids in the L5 Trojans DES sample, which have diameters in the 5 - 20 km range.

Mapping gas around massive galaxies: cross-correlation of DES Y3 galaxies and Compton- y -maps from SPT and it Planck by J. Sánchez et al. on Monday 17 October We cross-correlate positions of galaxies measured in data from the first three years of the Dark Energy Survey with Compton-$y$-maps generated using data from the South Pole Telescope (SPT) and the {it Planck} mission. We model this cross-correlation measurement together with the galaxy auto-correlation to constrain the distribution of gas in the Universe. We measure the hydrostatic mass bias or, equivalently, the mean halo bias-weighted electron pressure $langle b_{h}P_{e}rangle$, using large-scale information. We find $langle b_{h}P_{e}rangle$ to be $[0.16^{+0.03}_{-0.04},0.28^{+0.04}_{-0.05},0.45^{+0.06}_{-0.10},0.54^{+0.08}_{-0.07},0.61^{+0.08}_{-0.06},0.63^{+0.07}_{-0.08}]$ meV cm$^{-3}$ at redshifts $z sim [0.30, 0.46, 0.62,0.77, 0.89, 0.97]$. These values are consistent with previous work where measurements exist in the redshift range. We also constrain the mean gas profile using small-scale information, enabled by the high-resolution of the SPT data. We compare our measurements to different parametrized profiles based on the cosmo-OWLS hydrodynamical simulations. We find that our data are consistent with the simulation that assumes an AGN heating temperature of $10^{8.5}$K but are incompatible with the model that assumes an AGN heating temperature of $10^{8.0}$K. These comparisons indicate that the data prefer a higher value of electron pressure than the simulations within $r_{500c}$ of the galaxies' halos. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2210.08633v1
Dark Energy Survey Year 3 Results: Measurement of the Baryon Acoustic Oscillations with Three-dimensional Clustering by K. C. Chan et al. on Tuesday 11 October The three-dimensional correlation function offers an effective way to summarize the correlation of the large-scale structure even for imaging galaxy surveys. We have applied the projected three-dimensional correlation function, $xi_{rm p}$ to measure the Baryonic Acoustic Oscillations (BAO) scale on the first-three years Dark Energy Survey data. The sample consists of about 7 million galaxies in the redshift range $ 0.6 < z_{rm p } < 1.1 $ over a footprint of $4108 , mathrm{deg}^2 $. Our theory modeling includes the impact of realistic true redshift distributions beyond Gaussian photo-$z$ approximation. To increase the signal-to-noise of the measurements, a Gaussian stacking window function is adopted in place of the commonly used top-hat. Using the full sample, $ D_{rm M}(z_{rm eff} ) / r_{rm s} $, the ratio between the comoving angular diameter distance and the sound horizon, is constrained to be $ 19.00 pm 0.67 $ (top-hat) and $ 19.15 pm 0.58 $ (Gaussian) at $z_{rm eff} = 0.835$. The constraint is weaker than the angular correlation $w$ constraint ($18.84 pm 0.50$) because the BAO signals are heterogeneous across redshift. When a homogeneous BAO-signal sub-sample in the range $ 0.7 < z_{rm p } < 1.0 $ ($z_{rm eff} = 0.845$) is considered, $xi_{rm p} $ yields $ 19.80 pm 0.67 $ (top-hat) and $ 19.84 pm 0.53 $ (Gaussian). The latter is mildly stronger than the $w$ constraint ($19.86 pm 0.55 $). We find that the $xi_{rm p} $ results are more sensitive to photo-$z$ errors than $w$ because $xi_{rm p}$ keeps the three-dimensional clustering information causing it to be more prone to photo-$z$ noise. The Gaussian window gives more robust results than the top-hat as the former is designed to suppress the low signal modes. $xi_{rm p}$ and the angular statistics such as $w$ have their own pros and cons, and they serve an important crosscheck with each other. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2210.05057v1
Cosmic Shear in Harmonic Space from the Dark Energy Survey Year 1 Data: Compatibility with Configuration Space Results by H. Camacho et al. on Tuesday 11 October We perform a cosmic shear analysis in harmonic space using the first year of data collected by the Dark Energy Survey (DES-Y1). We measure the cosmic weak lensing shear power spectra using the Metacalibration catalogue and perform a likelihood analysis within the framework of CosmoSIS. We set scale cuts based on baryonic effects contamination and model redshift and shear calibration uncertainties as well as intrinsic alignments. We adopt as fiducial covariance matrix an analytical computation accounting for the mask geometry in the Gaussian term, including non-Gaussian contributions. A suite of 1200 lognormal simulations is used to validate the harmonic space pipeline and the covariance matrix. We perform a series of stress tests to gauge the robustness of the harmonic space analysis. Finally, we use the DES-Y1 pipeline in configuration space to perform a similar likelihood analysis and compare both results, demonstrating their compatibility in estimating the cosmological parameters $S_8$, $sigma_8$ and $Omega_m$. The methods implemented and validated in this paper will allow us to perform a consistent harmonic space analysis in the upcoming DES data. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2111.07203v2
The MADPSZ catalogue of Planck clusters over the DES region: extending to lower mass and higher redshift by D. Hernández-Lang et al. on Monday 10 October We present the first systematic follow-up of Planck Sunyaev-Zeldovich effect (SZE) selected candidates down to signal-to-noise (S/N) of 3 over the 5000 deg$^2$ covered by the Dark Energy Survey. Using the MCMF cluster confirmation algorithm, we identify optical counterparts, determine photometric redshifts and richnesses and assign a parameter, $f_{rm cont}$, that reflects the probability that each SZE-optical pairing represents a real cluster rather than a random superposition of physically unassociated systems. The new MADPSZ cluster catalogue consists of 1092 MCMF confirmed clusters and has a purity of 85%. We present the properties of subsamples of the MADPSZ catalogue that have purities ranging from 90% to 97.5%, depending on the adopted $f_{rm cont}$ threshold. $M_{500}$ halo mass estimates, redshifts, richnesses, and optical centers are presented for all MADPSZ clusters. The MADPSZ catalogue adds 828 previously unknown Planck identified clusters over the DES footprint and provides redshifts for an additional 50 previously published Planck selected clusters with S/N>4.5. Using the subsample with spectroscopic redshifts, we demonstrate excellent cluster photo-$z$ performance with an RMS scatter in $Delta z/(1+z)$ of 0.47%. Our MCMF based analysis allows us to infer the contamination fraction of the initial S/N>3 Planck selected candidate list, which is 50%. We present a method of estimating the completeness of the MADPSZ cluster sample and $f_{rm cont}$ selected subsamples. In comparison to the previously published Planck cluster catalogues. this new S/N $>$ 3 MCMF confirmed cluster catalogue populates the lower mass regime at all redshifts and includes clusters up to z$sim$1.3. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2210.04666v1
Dark Energy Survey Year 3 results: Magnification modeling and impact on cosmological constraints from galaxy clustering and galaxy-galaxy lensing by J. Elvin-Poole et al. on Wednesday 21 September We study the effect of magnification in the Dark Energy Survey Year 3 analysis of galaxy clustering and galaxy-galaxy lensing, using two different lens samples: a sample of Luminous red galaxies, redMaGiC, and a sample with a redshift-dependent magnitude limit, MagLim. We account for the effect of magnification on both the flux and size selection of galaxies, accounting for systematic effects using the Balrog image simulations. We estimate the impact of magnification on the galaxy clustering and galaxy-galaxy lensing cosmology analysis, finding it to be a significant systematic for the MagLim sample. We show cosmological constraints from the galaxy clustering auto-correlation and galaxy-galaxy lensing signal with different magnifications priors, finding broad consistency in cosmological parameters in $Lambda$CDM and $w$CDM. However, when magnification bias amplitude is allowed to be free, we find the two-point correlations functions prefer a different amplitude to the fiducial input derived from the image simulations. We validate the magnification analysis by comparing the cross-clustering between lens bins with the prediction from the baseline analysis, which uses only the auto-correlation of the lens bins, indicating systematics other than magnification may be the cause of the discrepancy. We show adding the cross-clustering between lens redshift bins to the fit significantly improves the constraints on lens magnification parameters and allows uninformative priors to be used on magnification coefficients, without any loss of constraining power or prior volume concerns. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2209.09782v1

Lessons Learned from the Two Largest Galaxy Morphological Classification Catalogues built by Convolutional Neural Networks by Ting-Yun Cheng et al. on Thursday 15 September We compare the two largest galaxy morphology catalogues, which separate early and late type galaxies at intermediate redshift. The two catalogues were built by applying supervised deep learning (convolutional neural networks, CNNs) to the Dark Energy Survey data down to a magnitude limit of $sim$21 mag. The methodologies used for the construction of the catalogues include differences such as the cutout sizes, the labels used for training, and the input to the CNN - monochromatic images versus $gri$-band normalized images. In addition, one catalogue is trained using bright galaxies observed with DES ($i
Characterising the Intracluster Light over the Redshift Range 0 2 < z < 0 8 in the DES-ACT Overlap by Jesse B. Golden-Marx et al. on Thursday 15 September We characterise the properties and evolution of Bright Central Galaxies (BCGs) and the surrounding intracluster light (ICL) in galaxy clusters identified in overlapping regions of the Dark Energy Survey and Atacama Cosmology Telescope Survey (DES-ACT), covering the redshift range $0.20
Marginal Bayesian Statistics Using Masked Autoregressive Flows and Kernel Density Estimators with Examples in Cosmology by Harry Bevins et al. on Wednesday 14 September Cosmological experiments often employ Bayesian workflows to derive constraints on cosmological and astrophysical parameters from their data. It has been shown that these constraints can be combined across different probes such as Planck and the Dark Energy Survey and that this can be a valuable exercise to improve our understanding of the universe and quantify tension between multiple experiments. However, these experiments are typically plagued by differing systematics, instrumental effects and contaminating signals, which we collectively refer to as `nuisance' components, that have to be modelled alongside target signals of interest. This leads to high dimensional parameter spaces, especially when combining data sets, with > 20 dimensions of which only around 5 correspond to key physical quantities. We present a means by which to combine constraints from different data sets in a computationally efficient manner by generating rapid, reusable and reliable marginal probability density estimators, giving us access to nuisance-free likelihoods. This is possible through the unique combination of nested sampling, which gives us access to Bayesian evidences, and the marginal Bayesian statistics code MARGARINE. Our method is lossless in the signal parameters, resulting in the same posterior distributions as would be found from a full nested sampling run over all nuisance parameters, and typically quicker than evaluating full likelihoods. We demonstrate our approach by applying it to the combination of posteriors from the Dark Energy Survey and Planck. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2207.11457v2

Dark Energy Survey Year 3 Results: Redshift Calibration of the MagLim Lens Sample from the combination of SOMPZ and clustering and its impact on Cosmology by G. Giannini et al. on Tuesday 13 September We present an alternative calibration of the MagLim lens sample redshift distributions from the Dark Energy Survey (DES) first three years of data (Y3). The new calibration is based on a combination of a Self-Organising Maps based scheme and clustering redshifts to estimate redshift distributions and inherent uncertainties, which is expected to be more accurate than the original DES Y3 redshift calibration of the lens sample. We describe in detail the methodology, we validate it on simulations and discuss the main effects dominating our error budget. The new calibration is in fair agreement with the fiducial DES Y3 redshift distributions calibration, with only mild differences ($
Characterising the Intracluster Light over the Redshift Range 0 2 < z < 0 8 in the DES-ACT Overla by Jesse B. Golden-Marx et al. on Tuesday 13 September We characterise the properties and evolution of Bright Central Galaxies (BCGs) and the surrounding intracluster light (ICL) in galaxy clusters identified in overlapping regions of the Dark Energy Survey and Atacama Cosmology Telescope Survey (DES-ACT), covering the redshift range $0.20
Dark Energy Survey Year 3 results: cosmology with moments of weak lensing mass maps by M. Gatti et al. on Sunday 11 September We present a cosmological analysis using the second and third moments of the weak lensing mass (convergence) maps from the first three years of data (Y3) data of the Dark Energy Survey (DES). The survey spans an effective area of 4139 square degrees and uses the images of over 100 million galaxies to reconstruct the convergence field. The second moment of the convergence as a function of smoothing scale contains information similar to standard shear 2-point statistics. The third moment, or the skewness, contains additional non-Gaussian information. The data is analysed in the context of the $Lambda$CDM model, varying 5 cosmological parameters and 19 nuisance parameters modelling astrophysical and measurement systematics. Our modelling of the observables is completely analytical, and has been tested with simulations in our previous methodology study. We obtain a 1.7% measurement of the amplitude of fluctuations parameter $S_8equiv sigma_8 (Omega_m/0.3)^{0.5} = 0.784pm 0.013$. The measurements are shown to be internally consistent across redshift bins, angular scales, and between second and third moments. In particular, the measured third moment is consistent with the expectation of gravitational clustering under the $Lambda$CDM model. The addition of the third moment improves the constraints on $S_8$ and $Omega_{rm m}$ by $sim$15% and $sim$25% compared to an analysis that only uses second moments. We compare our results with {it Planck} constraints from the Cosmic Microwave Background (CMB), finding a $2.2$ textendash $2.8sigma$ tension in the full parameter space, depending on the combination of moments considered. The third moment independently is in $2.8sigma$ tension with {it Planck}, and thus provides a cross-check on analyses of 2-point correlations. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2110.10141v2
En este episodio final del 2021 hablamos sobre la misión "Gaia", el proyecto "Cartografiado de La Energía Oscura" ("Dark Energy Survey", DES) y la controversia del parámetro de Hubble.
Dr Jeffery goes into detail about how dark energy and dark matter, two things he is researching extensively, are elusive and that astrophysicists know very little about it. The Dark Energy Survey is a project which he is part of that tries to map the distribution of dark energy in our universe. Dr Jeffrey also spoke about machine learning in the context of his research and how it is being used extensively throughout the projects he is working in.
Everything we see and interact with, regular matter, is only a small fraction of what the universe contains. In fact, the vast majority of the universe is invisible to us. We've named these mysterious components dark matter and dark energy, but our understanding of them – and if they even exist – remains lacking. To unravel more of this mystery, Dr Alfredo Carpineti sat down with Dr Mandeep Gill from the Dark Energy Survey collaboration to ask: Will the new generation of upcoming observatories help us understand what the universe is really made of?
Minor planet 2014 UN271, discovered in data collected by the Dark Energy Survey, is set to make a close pass to Saturn's orbit at the end of the decade, giving astronomers a chance to observe a rare trans-Neptunian object from up close...ish. Plus, Venus, Jupiter, the Milky Way, and an invisible galactic structure discovered quite by accident.

What would happen to our carbon emissions if we all went vegan? Astrophysicist, Sarah Bridle tells Jim Al-Khalili why she switched her attention from galaxies to food. A rising star in the study of extra-galactic astronomy, Sarah was a driving force behind one of the most ambitious astronomy projects of recent times, the Dark Energy Survey of the universe. A few years ago, she started trying to calculate the carbon emissions from different foods so that she could make more informed choices about what she was eating in terms of the impact they were having on climate change. Before long, she was adapting the statistical tools and techniques she had developed to study dark matter and dark energy, to quantify the carbon cost of different foods and lobby government to make food labels indicating carbon cost of foods compulsory.

También tenemos claro que esa estrella a la que damos vueltas es solo una de las cientos de miles de millones que forman nuestra galaxia, pero ¿qué hay más allá? ¿Cómo se relacionan todas estas galaxias entre sí? ¿Qué estructura tiene el universo a gran escala?Para ello tenemos con nosotros a Ana Salvador, que es licenciada en física, hizo un máster de física teórica y es doctora en cosmología por la Universidad Autónoma de Madrid. Se dedicaba a estudiar cómo se distribuyen las galaxias en el universo con datos de la colaboración Dark Energy Survey, a la que pertenecía. Mientras hacía el doctorado se dio cuenta de que la investigación no era lo suyo y empezó un máster de profesorado en la UNED mientras terminaba la tesis. Cuando terminó el doctorado puso en marcha el proyecto Acoge a un científico, en el que estuvo dos años y medio viajando por Latinoamérica divulgando ciencia. El proyecto terminó por la pandemia, pero siguió con la divulgación en su canal de youtube Anisotropía. Y ahora está haciendo un máster de cultura científica a la vez que estudia para las oposiciones de docentes de secundaria.)

Due studi basati sui dati del Dark Energy Survey ipotizzano che ci sono circa un centinaio di galassie mancanti ancora da osservare che se individuate potrebbero confermare il legame che collega la formazione galattica alla materia oscura
The next generation of surveys, e.g. the Dark Energy Survey, PanSTARRS, LSST, Euclid and others, aim to study the nature of Dark Energy and alternatives. The talk will discuss how the Dark Energy paradigm evolved over the past 20 years, and the cosmic probes which will help us to test it. In particular the surveys rely on accurate of photometric redshifts for the determination of cosmological quantities such as Dark Energy parameters and neutrino masses. The talk will describe photometric redshift methods and their impact on analysing galaxy clustering and weak lensing data and on the derived cosmological parameters.

The three UFO sightings that took place on April 20th came in not only three different cities, but on two completely different continents. Two of them took place in England, one in Coatbridge and another in City of Street, while the third UFO sighting of the night happened in Rives Junction, Michigan — all chronicled on the web site of UFO and alien expert Scott Waring. According to the eyewitness in Michigan who spotted a fleet of UFOs in the early evening sky (video can be viewed here)… I heard a weird sound Like A Pulsating hum. Thought it was coming from power substation across the street. Concerned I went to look. I opened my front door and Heard it Above the house looked up and There it was.

Close Encounters of the Fifth Kind Clip Reveals Unseen UFO Sighting Footage [Exclusive] Link: https://movieweb.com/close-encounters-of-the-5th-kind-ufo-sighting-video/ A sequel to UFO documentary Unacknowledged, Close Encounters of the Fifth Kind has landed on digital this week. Directed by Michael Mazzola and presented by Dr. Steven Greer, the global authority on extraterrestrials who created the worldwide disclosure movement and routinely briefs presidents and heads of state on the ET phenomenon, the film presents the most controversial information ever released to the public. Whistleblowers and scientific experts bring viewers face to face with extraterrestrial visitors and their message for humanity. His previous works, Sirius and Unacknowledged, broke crowdfunding records and ignited a grassroots movement. In Close Encounters of the Fifth Kind, Dr. Greer presents the most dangerous information that the architects of secrecy don't want you to know: how forgotten spiritual knowledge holds the key to humans initiating contact with advanced ET civilizations. Close Encounters of the Fifth Kind features groundbreaking video and photographic evidence and supporting interviews from prominent figures such as Adam Curry of Princeton's PEAR Lab; legendary civil rights attorney Daniel Sheehan, and Dr. Russell Targ, who headed the CIA's top secret remote viewing program. Their message: For thousands of people, contact has begun. This is their story. New study deepens the controversy over Planet Nine's existence Link: https://bigthink.com/surprising-science/planet-nine Astronomers release new data to challenge claims about the mysterious Planet Nine. Is there a mysterious Planet Nine hiding in the outskirts of our solar system? While there've been hypotheses making such claims, a new study looks to disprove its existence. The research from astronomers at the University of Pennsylvania strikes at the heart of the clues that led some to believe such a planet was there. From 2014, astronomers have been suggesting various explanations for the behavior of so-called "trans-Neptunian objects" (eTNOs) that are farther from the Sun than Neptune. These rocks in the outer reaches were previously found to be clumped together, traveling in an elongated orbit, as reports New Scientist. One reason for that could be that they were pulled by the gravity of a giant planet that is five to 10 times the mass of Earth. One fascinating idea proposed about such a possible planet is that it may be responsible for the extinction of the dinosaurs, as it knocks catastrophic comets towards Earth when it passes through the Kuiper belt once every 27 million years. The new research shows, however, that there may not be any clustering trans-Neptunian rocks at all. The scientists used data from the Dark Energy Survey, carried out at a Chilean observatory. The University of Pennsylvania astronomer Pedro Bernardinelli, the lead author of the paper, thinks their data doesn't bode well for Planet Nine's probability. "We would not have formulated the Planet Nine idea if our data was the only data that existed," said Bernardinelli to New Scientist. The scientist's previous 2020 study, also using data from the Dark Energy Survey, found 316 trans-Neptunian objects, including 139 minor planets in the space past Neptune. The researcher's works ultimately seems to show that the faraway region is inhabited by numerous small objects which are uniformly distributed rather than grouped. Samantha Lawler from the University of Regina, Canada, who was not involved in the study, also thinks there's still a chance the Planet Nine could still be out there. "The way that the Planet Nine hypothesis is constructed is that it's completely impossible to falsify it — the only way to prove it's not there is to search every square centimeter of the sky and not find it," she commented to New Scientist.

The psychology behind why toilet paper is the latest coronavirus panic buy Link: https://fox4kc.com/news/got-tp-the-psychology-behind-why-toilet-paper-is-the-latest-coronavirus-panic-buy/ People resort to extremes when they hear conflicting messages “On the one hand, [the response is] understandable, but on the other hand it's excessive,” Taylor, a professor and clinical psychologist at the University of British Columbia, told CNN. “We can prepare without panicking.” The novel coronavirus scares people because it's new, and there's a lot about it that's still unknown. When people hear conflicting messages about the risk it poses and how seriously they should prepare for it, they tend to resort to the extreme, Taylor said. “When people are told something dangerous is coming, but all you need to do is wash your hands, the action doesn't seem proportionate to the threat,” he said. “Special danger needs special precautions.” It allows some to feel a sense of control The people who are stocking up on supplies are thinking about themselves and their family and what they need to do to prepare, Taylor said — not healthcare workers, sick people or even regular folks who might run out of toilet paper sometime soon. “It's all due to this wave of anticipatory anxiety,” Taylor said. “People become anxious ahead of the actual infection. They haven't thought about the bigger picture, like what are the consequences of stockpiling toilet paper.” Elon Musk told Tesla employees they are more likely to die in a car accident than from the Coronavirus.

Flu season is hitting its stride right now in the US. So far, the CDC has estimated (based on weekly influenza surveillance data) that at least 12,000 people have died from influenza between Oct. 1, 2019 through Feb. 1, 2020, and the number of deaths may be as high as 30,000. The CDC also estimates that up to 31 million Americans have caught the flu this season, with 210,000 to 370,000 flu sufferers hospitalized because of the virus. Planet 9 discovery gets closer as astronomers discover 139 'minor planets' past Neptune Link: https://www.foxnews.com/science/planet-9-discovery-gets-closer-as-astronomers-discover-139-minor-planets-past-neptune Astronomers are getting closer to discovering the elusive and mysterious Planet Nine after 139 "minor planets" were discovered past Neptune's orbit. These objects, ones "that were not previously published," are not officially planets or comets, but rather space objects that orbit the Sun. In total, the discovery is five percent of the trans-Neptunian object (TNO) population, bringing the number to approximately 3,000, according to a statement accompanying the study. "Pluto, the best-known TNO, is 40 times farther away from the sun than Earth is, and the TNOs found using the [Dark Energy Survey] data range from 30 to 90 times Earth's distance from the sun," the statement reads. "Some of these objects are on extremely long-distance orbits that will carry them far beyond Pluto." The researchers used data from the DES between 2013 and 2017, which uses a 520-megapixel Dark Energy Camera. It is on the Blanco 4-meter telescope at the Cerro Tololo Inter-American Observatory in Chile. There were 7 billion DES-detected dots that the researchers started with, a list that was condensed to 22 million "transient" objects and then eventually, approximately 400 objects that were observed over six separate nights. SpaceX readying for Sunday's sixth Starlink launch, first fifth booster flight Link: https://www.nasaspaceflight.com/2020/03/spacex-sixth-starlink-fifth-booster-reflight/ SpaceX is preparing its Falcon 9 to launch the Starlink V1.0 L5 mission, although the launch date has been moved to Sunday. This mission will be the first Starlink launch from LC-39A at Kennedy Space Center, and the first from the pad since the Crew Dragon In-Flight Abort Test in January 2020. The first stage is B1048.5 – marking the first time a Falcon 9 core flies for the fifth time. The launch is now scheduled for 9:22 AM Eastern on March 15. SpaceX is continuing to ramp the rate of Starlink launches as they work toward completing Phase 1 – a constellation of nearly 1600 satellites in a 550km-high orbit. SpaceX will assign the satellites to one of three orbital planes. Orbital planes are to satellites as tracks are to trains – they are orbits parallel to each other designed to maximize area coverage while minimizing the number of satellites required. SpaceX plans to begin offering Starlink service to Canada and the northern United States later this year. Near global coverage is expected to start next year. Pricing has not been made public, but it has been hinted that speeds up to one gigabit may be possible.

In dieser Folge spricht Jochen Weller von der Universitätssternwarte München über eine bislang unbekannte Energieform, die der Schwerkraft entgegenwirkt und die Expansion des Universums beschleunigt.
We've known since Edwin Hubble's time that the universe has been expanding. What we've only recently learned (like, in the past 10 years or so) is that the universe is accelerating as it expands. Measuring this expansion rate has been problematic and while there are at least two different ways to make the measurement, they don't always agree. This episode features Ed Macauley from the University of Portsmouth UK, and a member of the Dark Energy Survey collaboration. He and his team have been using a calibrated version of the 'standard candle' method of determining the rate of universal expansion, also known as the Hubble Constant or H0 to get a better answer that agrees with other measurement techniques.

*Does New Horizon’s next target have a moon? There’s growing speculation that the next target for NASA’s New Horizons spacecraft might be very unusual. *First hints of the quasiparticle Physicists say they’ve found their first tantalizing hints for the existence of quasiparticles called odderons. The findings are based on subatomic particle collisions undertaken at the Large Hadron Collider – the world’s largest atom smasher. *Stellar Streams in the Milky Way Astronomers have discovered 11 new stellar streams in our galaxy the Milky Way. The findings were discovered in the first three years of data obtained by the Dark Energy Survey. *Long lost image satellite found NASA has confirmed a satellite spotted last month -- is the agency’s long lost Imager for Magnetopause-to-Aurora Global Exploration or IMAGE spacecraft. *Earthquake early warning satellite launched China has launched a satellite testing a potential earthquake early warning system which could save thousands of lives a year. *Falcon 9 launches Luxembourg military satellite A SpaceX Falcon 9 rocket has launched a new telecommunications satellite for Luxembourg’s military.

A Wednesday Lunch at the Divinity School featuring Joshua Frieman, Director of the Dark Energy Survey and Professor of Astronomy and Astrophysics at the University of Chicago, speaking on "The Dark Energy Survey and the Mystery of the Accelerating Universe." The discovery that the universe is accelerating, not slowing down from the mass it contains, is the surprise that sets the initial research program of 21st Century cosmology. The Dark Energy Survey is a next generation sky survey aimed directly at understanding this mystery. Their quarry is the dark energy, the reasons the universe is accelerating.
I find out how the British Geological Survey is investigating the threat that solar storms pose to the world's electricity grids. David Southwood, President of the RAS, tells me that astronomy is about much more than just understanding the Universe: it also has a huge economical impact. And, how is the Dark Energy Survey pinning down the make up of the Universe? Like this podcast? Please help us by supporting the Naked Scientists

Abstract: The discovery of accelerated cosmic expansion showed us that cosmology remains incomplete. A new element is required. This may be a cosmological constant, a more exotic form of dark energy, or a failure of general relativity on large scales. Galaxy clusters provide a powerful tool for discriminating among these possibilities. I will describe the strengths and weaknesses of clusters as cosmological probes, illustrate these with recent analyses of SDSS clusters, and discuss the prospects for future constraints, especially in the Dark Energy Survey project. Dr. McKay is Arthur F. Thurnau Professor of Physics. His scientific research focuses on fundamental questions of observational astrophysics and cosmology. . Presented October 9, 2009.
We've got another bumper show for you starting with some interviews we recorded at the Modern Radio Universe conference. We talk to the Astronomer Royal, find out about adapting spacecraft technology to track TB on Earth, the successor to SMART1, and how astronomers and particle physicists are using the Moon as a huge neutrino detector. We listen to audience comments on the fantastic Space 50 event where the Lovell Telescope was turned into a giant projector screen and then we have our main interview about the Dark Energy Survey. We also have an announcement about an event being held in Macclesfield on 27th October. Finally, we answer your questions in Ask an Astronomer.
