StarXiv: a podcast discussing the latest astronomy papers

In this episode, Michelle and Nicole discuss machine learning methods to classify merging galaxies and different classes of supernova. They also look into whether planetary engulfment can explain unsual chemical signatures in some binary systems, and dive deep into some beautiful MUSE data for a spiral galaxy at redshift 0.09.

In this episode, Michelle and Nicole were on-theme with their paper choices. They discuss whether and how stars from ancient globular clusters populate the stellar halo of the Milky Way, and look into research on growing massive black hole seeds in the smallest dwarf galaxies.

In this episode, Payel and Nicole delve into more JWST discoveries and the frontier of machine learning in astronomy - an ultra-deep view of the cosmic web, machine-learning deep images to look for mergers, a direct collapse black hole explanation to Little Red Dots, machine-learning the Milky Way to reveal complex star formation histories of accreted systems, and the earliest nuclear stellar disc observed to date.

In this episode, Michelle and Payel both dissect interesting results from varying stars, including follow up on Betelgeuse's elusive companion. They also talk about the imprints of digested and transiting stars on their hosts spectra, and an unusual lensing signal that could pose difficult questions for warm and cold dark matter.

In this episode, Michelle and Nicole dissect 5 papers, and accidentally find a common theme: disks! Whether in low mass galaxies, giant low surface brightness galaxies, the rotation curves of spirals or the natal environment of planetary systems, disks really are all around us. They also discuss the differences in chemistries between globular clusters that have been accreted or formed in-situ, just for a little bit of balance.

In this episode, Michelle and Payel squash in more papers than ever, as Michelle delves into a flurry of papers about new newly discovered interstellar comet: 3I/ATLAS. They also discuss what sets the metallicities of the faintest galaxies, how nitrogen enrichment relates to gas density, the molten properties of a new ultra-short period planets, and how to find 'dak' galaxies!
