Se trata de uno de los estallidos rápidos de radio (FRB) más potentes detectados hasta ahora, y se acaba de confirmar que también el más lejano. Con su ayuda, los científicos podrán detectar la 'materia perdida' del UniversoLa emisión duró apenas una milésima de segundo. Pero en ese breve lapso de tiempo, una súbita ráfaga de radio espacial (FRB por sus siglas en inglés) liberó una cantidad de energía equivalente a la que el Sol es capaz de producir en 30 años. El estallido, denominado FRB 20220610A, fue captado el pasado 10 de junio de 2022 por el radiotelescopio ASKAP, una red de 36 antenas de radio de 12 metros cada una situada en Australia, pero entonces no fue posible determinar su origen.Ahora, más de un año después, un equipo internacional de científicos ha sido capaz de localizar la fuente de aquel suceso. Usando el Very Large Telescope (VLT) del Observatorio Europeo Austral (ESO), en Chile, los investigadores pudieron comprobar que FRB 20220610A es la ráfaga rápida de radio más distante (y por lo tanto más antigua) jamás detectada. De hecho, inició su viaje hacia nosotros hace 8.000 millones de años, mucho antes de que el Sol y la Tierra empezaran siquiera a existir. A esa increíble distancia, que multiplica por dos la del hasta ahora FRB más lejano, la poderosa ráfaga es, también, una de las más energéticas observadas hasta ahora.El impactante descubrimiento, llevado a cabo por un equipo internacional de científicos dirigido por Stuart Ryder y Ryan Shannon, de las universidades australianas Macquaire y Swinburne, se acaba de publicar en la revista 'Science'.

CSIRO's 36-dish ASKAP telescope – or Australian SKA Pathfinder telescope – has spotted a galaxy that may be surrounded by a “polar ring” of gas.   In this episode of the Space Connect podcast, Dr Bärbel Koribalski, a co-author of the project, explains what this means and how it can shape our understanding of the universe.

Researchers using the 36-dish ASKAP telescope have made a discovery that challenges the hypothesis around how “fast radio bursts” form. Fast radio bursts are intense bursts of radio emission that can last just milliseconds and were only first detected in 2007. The exact processes that cause them have long been shrouded in mystery. Traditionally, they have only been recorded in colliding galaxies, but now, an Australian-based team have detected them in a much calmer galactic environment. In this episode, Curtin University's Marcin Glowacki, who led the study, and Dr Karen Lee-Waddell, explain the significance of the findings.

Astrophiz 160: CSIRO-ASKAP Recap: The journey so far with Australia's newest radio telescope Australia's ASKAP (Australian SKA Pathfinder) radio telescope array has had an amazing decade since first light, breaking records, receiving awards and finding new objects, all whilst still in its pilot phase. In this fabulous episode you will hear from the scientists using ASKAP every day to conduct groundbreaking research to further their studies, and from those working to shape ASKAP into a truly remarkable national facility and international resource. You will discover how this Earth-based telescope assists astronomers in ways we didn't know was possible a decade ago. As a precursor instrument to the SKA project - what will be continent spanning arrays comprising the largest telescope the world has ever seen - the lessons we've learnt from ASKAP are informing the next stages of radio astronomy. This program is hosted by Rachel Rayner, whose enviable job is to bring you the best stories about the telescopes that make up the Australian Telescope National Facility. You will hear from four wonderful speakers working with ASKAP.

Deep Investigation of Neutral Gas Origins DINGO : HI stacking experiments with early science data by Jonghwan Rhee et al. on Tuesday 18 October We present early science results from Deep Investigation of Neutral Gas Origins (DINGO), an HI survey using the Australian Square Kilometre Array Pathfinder (ASKAP). Using ASKAP sub-arrays available during its commissioning phase, DINGO early science data were taken over $sim$ 60 deg$^{2}$ of the Galaxy And Mass Assembly (GAMA) 23 h region with 35.5 hr integration time. We make direct detections of six known and one new sources at $z < 0.01$. Using HI spectral stacking, we investigate the HI gas content of galaxies at $0.04 < z< 0.09$ for different galaxy colours. The results show that galaxy morphology based on optical colour is strongly linked to HI gas properties. To examine environmental impacts on the HI gas content of galaxies, three sub-samples are made based on the GAMA group catalogue. The average HI mass of group central galaxies is larger than those of satellite and isolated galaxies, but with a lower HI gas fraction. We derive a variety of HI scaling relations for physical properties of our sample, including stellar mass, stellar mass surface density, $NUV-r$ colour, specific star formation rate, and halo mass. We find that the derived HI scaling relations are comparable to other published results, with consistent trends also observed to $sim$0.5 dex lower limits in stellar mass and stellar surface density. The cosmic HI densities derived from our data are consistent with other published values at similar redshifts. DINGO early science highlights the power of HI spectral stacking techniques with ASKAP. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2210.09697v1

New ASKAP Radio Supernova Remnants and Candidates in the Large Magellanic Cloud by Luke M. Bozzetto et al. on Monday 17 October We present a new Australian Square Kilometre Array Pathfinder (ASKAP) sample of 14 radio Supernova Remnant (SNR) candidates in the Large Magellanic Cloud (LMC). This new sample is a significant increase to the known number of older, larger and low surface brightness LMC SNRs. We employ a multi-frequency search for each object and found possible traces of optical and occasionally X-ray emission in several of these 14 SNR candidates. One of these 14 SNR candidates (MCSNR J0522-6543) has multi-frequency properties that strongly indicate a bona fide SNR. We also investigate a sample of 20 previously suggested LMC SNR candidates and confirm the SNR nature of MCSNR J0506-6815. We detect lower surface brightness SNR candidates which were likely formed by a combination of shock waves and strong stellar winds from massive progenitors (and possibly surrounding OB stars). Some of our new SNR candidates are also found in a lower density environments in which SNe type Ia explode inside a previously excavated interstellar medium (ISM). arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2210.05090v2

A pilot ASKAP survey for radio transients towards the Galactic Centre by Ziteng Wang et al. on Tuesday 06 September We present the results of a radio transient and polarisation survey towards the Galactic Centre, conducted as part of the Australian Square Kilometre Array Pathfinder Variables and Slow Transients pilot survey. The survey region consisted of five fields covering $sim265,{rm deg}^2$ ($350^circlesssim llesssim10^circ$, $vert bvert lesssim 10^circ$). Each field was observed for 12,minutes, with between 7 and 9 repeats on cadences of between one day and four months. We detected eight highly variable sources and seven highly circularly-polarised sources (14 unique sources in total). Seven of these sources are known pulsars including the rotating radio transient PSR~J1739--2521 and the eclipsing pulsar PSR~J1723--2837. One of them is a low mass X-ray binary, 4U 1758--25. Three of them are coincident with optical or infrared sources and are likely to be stars. The remaining three may be related to the class of Galactic Centre Radio Transients (including a highly likely one, VAST~J173608.2--321634, that has been reported previously), although this class is not yet understood. In the coming years, we expect to detect $sim$40 bursts from this kind of source with the proposed four-year VAST survey if the distribution of the source is isotropic over the Galactic fields. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2209.02352v1

Det australsk baserede radioteleskop, ASKAP, offentliggjorde for nyligt, at det var lykkedes at kortlægge over tre millioner galakser hvoraf en million er helt nyopdagede galakser. De udgør 83% af det synlige univers. Kortlægningen tog bare 300 timer, hvilket er langt hurtigere end man før har været i stand til. Men ASKAP er kun en test for det endnu større SKA radioteleskop, der skal stå færdigt en gang i 2027. Hvad er radioastronomi og hvad skal vi bruge det til - spørgsmålene er mange og for at få svar og blive klogere på emnet, har Morten Remar talt med Ole J. Knudsen, der er videnskabsformidler ved Institut for Fysik og Astronomi på Århus Universitet og ved en masse om emnet. Foto kredit: Århus Universitet

The Australian Square Kilometre Array Pathfinder (ASKAP) has mapped around three million distant galaxies with remarkable speed and detail. The telescope completed its first survey of the sky from the Outback in Western Australia in just 300 hours. According to Larry Marshall, head of Australian science agency Commonwealth Scientific and Industrial Research Organisation (CSIRO), the survey was a breakthrough in unveiling the mysteries of the universe. The survey's result is analogous to a Google Map of the universe, where millions of faraway galaxies are shown as star-like marks. The map includes about a million new galaxies that had never been seen before. Other telescopes would have taken about a decade to map out the same number of galaxies. In addition, compared to other surveys of the sky that require tens of thousands of images to process and combine, the ASKAP only needed about 900 images to create a new atlas of the sky. Because of its superior capabilities, astronomer David McConnell described the ASKAP as a game-changer in astronomy. The telescope is equipped with CSIRO-designed receivers that enable it to have a vast field of view and capture images of the sky in higher resolution compared to other telescopes. Its custom-built software is also capable of quickly processing the large amounts of data it generates. McConnell said the telescope is more sensitive, capturing a larger number of objects than ever before. Scientists at CSIRO expect to conduct more surveys of the sky and discover millions more galaxies in the future.  They are also hopeful that the telescope will allow them to observe changes in the sky and gain a better understanding of the life cycle of stars and the evolution of black holes and galaxies.

We start off the year with a mystery. What are ORCs? Odd Radio Circles a million light years across and far, far away. Now with more powerful telescopes coming online like MeerKAT in South Africa and ASKAP in Australia we are finding new things in the cosmos. Here to tell us about ORCs is Ray Norris, a Professor at Western Sydney University.

De Australische telescoop ASKAP heeft in 1 klap miljoenen nieuwe sterrenstelsels waargenomen. Daardoor is er nu een soort kaart van het zuidelijke deel van de hemel ontstaan. We hebben contact met Dr. Lucas Ellerbroek, sterrenkundige aan de UvA.

Dr Shivani Bhandari is a fabulous CSIRO research postdoctoral fellow who searches for and tracks down the location of fast radio bursts and other transients using the Australian Square Kilometre Array Pathfinder (ASKAP). She tells us a wonderful story of growing up in New Dehli, how she came to love the sky and her education and her Bachelor’s degree, her short stint in industry, then learning how to image the sky at radio wavelengths and her move to Australia for an ICRAR internship then achieving her PhD from Swinburne University in Melbourne supervised by Professors Tara Murphy and Matthew Bailes. Shivani invites us to put our propellor hats on as she reveals the novel real-time techniques she uses to detect and pinpoint the locations of extragalactic FRBs using the ASKAP array in an absolute radio quiet zone in outback Western Australia, then within minutes calling on instruments from all over the world to examine the same patch of sky at X-ray, gamma-ray photons and neutrinos on timescales ranging from an hour to a few months post-burst. We discuss the conclusions that have been drawn from studying the environments of both singular and repeating FRBs and how magnetars are becoming the prime suspects for the genesis of FRBs. Her descriptions of her visits to ASKAP and the rewards of her outreach work in the local schools in this remote region are simply wonderful. Enjoy

Esta semana os hablamos de uno de los descubrimientos más recientes en astronomía: los extraños círculos de radio, o ORCs (por sus siglas en inglés). Se trata de... bueno, círculos que emiten radio. Y que son extraños porque no sabemos lo que son. Se han descubierto gracias a la red de radiotelescopios ASKAP, en Australia, y en el episodio de hoy tenemos a un radioastrónomo, Héctor Vives, para hablar de qué sabemos sobre ellos y qué tipo de fenómeno podría estar detrás. Veréis que en el episodio de hoy tuvimos algunos desajustes técnicos, pero en esta versión hemos reparado algunos de ellos, así que esperamos que la experiencia sea más satisfactoria que en directo :) Si queréis aprender sobre otros fenómenos en radio que todavía no entendemos bien podéis escuchar el capítulo s01e19, en el que hablamos sobre las misteriosas ráfagas rápidas de radio. Este programa se emitió originalmente el 28 de julio de 2020. Podéis escuchar el resto de audios de Más de Uno en su canal de iVoox y en la web de Onda Cero, ondacero.es

We hear about her move over to Dwingeloo in the Netherlands to work as a telescope scientist with ASTRON, working with the Apertif upgrade on the WSRT and LOFAR, We look at the Big Data issues growing in radio astronomy and her vision to harness VR as a way of visualising both data, workflow and instrument training. We hear about her current Milky Way Halo research, the SEAFOG project and working on the FLASH team.

Today in Astrophiz we have our regular presenter Dr Ian 'Astroblog' Musgrave giving us is a special report on 'The Return of Betelgeuse' . Ian also previews the excellent observing opportunities over the next two weeks, especially in the morning skies, and a report on a captured 'mini-moon' IN THE NEWS: ASTRONOMERS DETECT BIGGEST EXPLOSION IN THE HISTORY OF THE UNIVERSE Scientists studying a distant galaxy cluster have discovered the biggest explosion seen in the Universe since the Big Bang. The blast came from a supermassive black hole at the centre of a galaxy 390 million light-years away in the Ophiuchus galaxy cluster. Next up, the FRB mystery intensifies We’ve been reporting on FRB’s since 2016 and interviewed leading FRB researchers, starting with Dr Manisha Caleb and her work using the Molonglo Synthesis Telescope. Since then, many new and old instruments like FAST, OVRO, CHIME, Greenbank, Arecibo, ASKAP and Parkes have all successfully joined in the search for FRBs. A paper on the 16-day repeater is on the archive pre-print server at tinyurlDOTcom/frbrepeater

Astrophiz 93: Dr Jim Palfreyman: The Vela Glitch This episode features astrophysicist Dr Jim Palfreyman, who is a data analyst and casual researcher at the University of Tasmania. Today he tells us about his celebrated Nature paper revealing the way he analyses Vela’s glitches and how that came to tell us about the inner structures of neutron stars/pulsars. In the sky for observers and astrophotographers: Our regular feature ‘What’s Up Doc’ is with Dr Ian ‘Astroblog’ Musgrave. He previews the excellent planet viewing opportunities over the next two weeks under moonless skies, how to find Vesta at its brightest, the variable star Mira approaches maximum and he gives us an update on our first interstellar comet 2I/Borisov, reaching maximum brightness in early December In the News: We have news from the grave. Two years ago we all watched sadly and triumphantly as Cassini speared into a fiery death into Saturn, and you might want to listen again to Episode 43 where we were guests at the NASA tracking station at Tidbinbilla. The news is that Cassini legacy just keeps on sciencing on. There’s a new paper in the Monthly Notices of the Royal Astronomical Society by Khawaja et al about a data analysis that revealed that Saturn’s moon Enceladus is erupting a plume of gas and ice grains from its south pole. Now we already knew that an that these plumes originate in the moon’s subsurface global ocean, and plume material travels through cracks in the icy crust and is ejected into space. What’s new is that the Cassini spacecraft’s Ion and Neutral Mass Spectrometer (INMS) detected volatile, gas phase, organic species in the plume and the Cosmic Dust Analyser (CDA) discovered high-mass, complex organic material in a small fraction of ice grains. Now these amines, carbonyls, and aromatic compounds could be ideal precursors for organic compounds in the warm depths of Enceladus’ ocean. So Life on Enceladus? We don’t know yet, but Cassini’s legacy doesn’t just live on, it’s shouting science very loudly. Stay tuned to Cassini’s echoes, there’s more to come! Next Episodes: Our very next episode is a fabulous interview with Amanda Wherrett who is a magnificent storyteller who paints a vivid picture of the Dark Sky Siding Spring Observatory, its amazing array of research telescopes and instruments, and the research happening there high on top of the Warrumbungle Ranges in remote New South Wales in Australia. And the episode after that we have Steve Olney, the amateur radio astronomer who captured the Vela Glitch that we talked about in this episode, as it happened. And he did it from his home-made radio telescope in his back yard. This is Citizen Science writ large and another great episode to look forward to. You can also look forward to our first ‘Are We Alone’ feature episode with Professor Geraint Lewis, over in the UK we will talk with Dr Belinda Nicholson and hopefully soon we will also have Suzy Jackson on a show for you, to talk about her work as an engineer on the MRO, ASKAP and the New Norcia tracking station. Stay tuned!

Astrophiz 91: Dr Chenoa Tremblay – “Molecules in Space & Dark Magnetism” Listen: Our fabulous featured guest today is Dr Chenoa Tremblay, who is a Postdoctoral fellow in Dark Magnetism with the CSIRO and a member of the Commissioning team for the Australian Square Kilometre Array Pathfinder (ASKAP) facility in remote Western Australia. Chenoa introduces us to Polarisation and Dark Magnetism and Astrochemistry and tell us how she uses the ASKAP array to detect and identify complex molecules in space. We also take a look at some of her earlier research where she provided proof that high-mass stars can form in isolation. Her most recent research as a CSIRO Fellow involves using the SKA precursor ASKAP telescopes to conduct observations of our Galaxy at 724 MHz to detect and characterise the polarimetric properties of carbyne in the Milky Way, and we also hear about her work with the GASKAP Spectral Line Survey Chenoa also does an array of fantastic outreach work in the community and schools and is the contact person for the CASS biennial Radio Astronomy School at the Australia Telescope Compact Array near Narrabri, NSW. Listeners who are physics graduates are too late for this year’s school, but can look forward to next time in 2021. Follow @Chenoachem on Twitter Our regular feature "What’s Up Doc” for Astrophotographers and Observers is presented by Dr Ian Musgrave, where he tells us what to look for in the night and morning skies for the next two weeks, and in ‘Ian’s Tangent for this episode, he tells us about Tardigrades on the Moon. Follow @ianfmusgrave on Twitter In the news: .1. We report on a Nature paper about Giant Bubbles (as in freaking GINORMOUS!) found at the centre of our galaxy by astronomers using the MeerKAT (SKA precursor) telescope in South Africa. .2. The film Ad Astra has triggered some science purists. It’s a film. It’s entertainment. There is no rule that says films have to be scientifically accurate. Just go and enjoy the film.

Hosts: Ed Brown, Penny Dumsday, Lucas Randall, Jo Benhamu 00:00:26 A seemingly successful treatment of a nasty genetic disease would not have been possible without zebrafish. 00:10:52 It may seem counterintuitive, but a strain of virus linked to the common cold has been used to treat patients with a type of bladder cancer. 00:20:44 Fast Radio Bursts - the strong blasts of radio waves from distant galaxies - have mystified astronomers since they were first detected in 2007. But now for the first time, an FRB has been traced back to its host galaxy, 3.6 billion light years away! 00:33:39 Psychologists have conducted a large survey of nearly 2,000 volunteers to determine which animals and insects people are most afraid of, and most disgusted by. Perhaps unsurprisingly, it didn't go well for spiders. This episode contains traces of astronaut Buzz Aldrin talking about the meaning of the Apollo 11 moon landing.

On this episode we answered a few question's from our #askAP, we talked about Area 51, how to tell when someone you're talking to is just doing it for the cap up, this weeks things we not fucking with & Much More! Dont forget to follow us on IG @1passivepodcast

on the first episode of 2019, we talk resolutions, #AskAP, 4 min's with Kim(saving money & bird box true meaning), Meek on twitter and Much More! Follow us on IG @1passivepodcast YouTube is AggressivelyPassiveTV

Presented on 19 October 2018 by Dr Michelle Cluver. The more we learn about the universe, the mosre it tends to surprise us. This is one of the most exciting aspects of science - making unexpected discoveries! In this talk I will present some recent scientific discoveries I have been involved with and discuss why these and other discoveries have us so excited about the Square Kilometre Array Pathfinders, MeerKAT and ASKAP.

Presented on 4 December 2015 by Dr Lisa Harvey-Smith. What is Dark Matter? How did the solar system form? Was Einstein right about the nature of gravity? Are we alone in the universe? To tackle these fascinating questions and more, an international consortium of eleven nations is currently designing the 'Square Kilometre Array' (SKA) telescope. Comprising thousands of radio receivers located in Africa and Australia, the SKA will be the world's most powerful radio telescope. It will revolutionise our understanding of the universe, from the first stars and galaxies formed after the Big Bang to the formation of planet Earth. In preparation for this mega-science project, the CSIRO has built the Australian SKA Pathfinder (ASKAP) telescope which is due to start early science operations next year. In this talk, CSIRO astronomer Dr. Lisa Harvey-Smith will reveal early results from ASKAP, explain the science and technology behind the telescope and describe many scientific mysteries it will tackle.

We recorded a special "AMA" episode that goes through a whole bunch of questions asked to us either on the website or Twitter (using the #AskAP hashtag). We want to say thanks to everyone that asked us any questions, we'll definitely be doing this again in the future -- so if you have feedback, let us know! Thank you to everyone that listened or gave this podcast a try this year, I think I speak for all three of the hosts when I say that it really means a lot that you took some time to let us rant in your ears. I want to wish everyone a great and safe holiday. - Jason Show Notes: absolutepunk.net/podcast/65 Subscribe on iTunes: apdot.net/podtunes Show Archive: apdot.net/podlink If you like our show, please rate it in iTunes, it really does help!
