    Episode 100: Be There or Be Ten Squared

    Astrobites turns 100! For our ten squared-th episode we take a tour of all of the extremes of astrophysics: the heaviest and the lightest, the fastest and the slowest, the brightest and dimmest. In doing so, Shashank covers an astrobite on itty bitty particles that pack a big punch, Lucia talks about medium-ish galaxies and their black hole hearts, and Cormac panics about the danger of violent kilonovae. To help us celebrate, we meet up with some old friends to discuss dark matter, exoplanets, and how ridiculously long a Ph.D. takes.  Astrobites: https://astrobites.org/2024/06/06/agns-quenching-dwarf-galaxies/ https://astrobites.org/2013/06/04/cosmic-rays-from-the-telescope-array/ https://astrobites.org/2023/11/20/kilonova-safety/ https://astrobites.org/2018/08/16/do_the_milky_ways_stellar_streams_have_that_fuzzy_dark_matter_feeling/ https://astrobites.org/2022/11/28/evaporating-exoplanet/ Space sound: http://soundcloud.com/alexhp-1/supernova-sonata MIT study on children thinking logarithmically: https://news.mit.edu/2012/thinking-logarithmically-1005#:~:text=Cognitive%20scientists%20theorize%20that%20that's,is%2031%2C%20or%203.

    Episode 99: The Grand Finale

    Danger - explosive! This week’s episode is all about supernovae. These star-ripping, neutrino spewing explosions are important to various fields of astrophysics. Cormac, Cole, and Lucia discuss just when stars actually go supernova. And also, whether we can use gravitational waves to tell which compact object is left behind. Everybody gets to share their favourite supernova science and (as we all love to do) to complain about how much astronomers love old, inconsistent nomenclature. Enjoy!   Intro questions: Powering a Supernova https://astrobites.org/2024/10/04/how-to-power-supernovae/ The explodability criterion: How to make a star go supernova https://astrobites.org/2024/09/13/explodability-criterion/ Can we perform a Supernova Autopsy Via Gravitational Waves? https://astrobites.org/2024/10/08/gwautopsy/ Space Sound: https://youtu.be/S-saaAyaW0c

    Episode 98: When PIGS Fly

    In this episode, Cormac, Shashank and Cole dig deep into Galactic Archaeology as we look into the past of our Milky Way. Cole brings us a catastrophic computational collision, while Shashank gives us the low-down on low-metallicity, and we see just how the (Gaia) sausage gets made. We also discuss the rights, wrongs and funnies of Astronomers trying to name things, and the diverse design philosophies behind some of our favourite observational facilities.

    Episode 97: Cosmic Time Machines

    In this episode, Shashank, Cole and Lucia bend time in their debut podcast together as we talk about the various ways astronomy is like time travel. Lucia gives us a peek into the past with the storied supernova Cas A, while Cole brings us on a nostalgic quest into gravitational wave memory. We hope you enjoy time traveling with us!   Astrobites:    https://astrobites.org/2024/08/26/cas_a_jwst/   https://astrobites.org/2024/08/28/gwmem/   Space sound:   https://www.youtube.com/watch?v=x9vGpkQurfc JWST Cas A images:   https://webbtelescope.org/contents/media/images/2023/149/01HGGZ4TPD8XFNPCBTZ2QYM0ZM   https://webbtelescope.org/contents/media/images/2023/121/01GWQBBY77MHGFV3M3N63KDCEJ

    Episode 96: kiErsten’s Exoplanetary Elemental Exit Episode

    This episode marks Kiersten’s last astro[sound]bites episode (and also side note – we’re posting this on her birthday!). To recognize Kiersten for her incredible time as a co-host, we take a journey through her academic paper trail by discussing her papers on how magma and metallicities affect how we think about exoplanetary formation and observations. Then we take a deep dive into Kiersten’s time as a co-host and graduate student including her stance on “publish or perish” and what she’s most excited about starting her NASA Sagan Postdoctoral Fellowship this fall.   Kiersten’s Papers:  https://arxiv.org/pdf/2307.13726 https://arxiv.org/pdf/2407.13821

    Episode 95: IMPReSsive Research

    In this week's episode, we take you on a two-part journey to Europe! First, Lucia and Cormac guide you through the differences of graduate programs in Europe and the US. Then, we jump into a series of mini-interviews with fellow PhD students about their research. We journey through a wide range of topics, including black holes big and smalls, the powerful winds of massive stars, and much more. If you would like to learn more about any of these topics, check out the links below! The mini-interviews were conducted as part of the IMPRS-Astro Hackathon, an unconference organised by Cormac and a few colleges, which brought together students from Heidelberg and Munich.

    Episode 94: The Floor Is Lava!

    Was the floor in your childhood home ever lava? If so, you may have been training to visit these spicy magma-filled exoplanets! In this episode, we're turning up the heat and investigating what makes magma/lava so important for potential extraterrestrial life. Sabrina takes us to the poster child of strange lava worlds and finally gives exoplanteers an answer to the long debate of whether it has an atmosphere or if its star blew it away. Then, Cormac tells us all about how water can play well with magma. Kiersten is convinced that these lava worlds might just be the perfect place for a hot summer vacation.   Astrobites: https://astrobites.org/2024/06/19/template-post-17/ https://astrobites.org/2023/09/21/magma-oceans-and-surface-water/   Kiersten’s paper:  https://iopscience.iop.org/article/10.3847/1538-4357/acea85/pdf   Space sound: https://www.bbc.co.uk/programmes/articles/3clDSXN26N9lQtCwJgMb2tR/sonification

    Episode 93: Itsy Bitsy Teeny Weeny Primordial Black Hole Machiney

    In this week’s episode, we take a look at the hottest trend in dark matter candidates - Primordial Black Holes. They’re like black holes, only smaller (in some cases)! Join us as we see what all the fuss is about. Kiersten shares a story of a black hole playing video games inside a star and glitching out of the mainframe, while Shashank makes his a[s]b debut with an explosive transient conundrum that *might* explain the mystery of dark matter once and for all. We round off with a discussion about our favourite pet dark matter theories and the merits of direct experimental searches.
