In this episode, Payel and Nicole discuss what happens to the metallicity gradient of a satellite galaxy after it merges with its host, the existence of intermediate-age RR lyrae and radio rings, the possibility of determining the history of the inner Milky Way from radially migrated stars, and the possibility of finding more Einstein rings using a new approach that utilises both spectra and images.

This episode, Michelle and Payel reunite to discuss the chemistry of nearby M-dwarf stars, where the majority of stars form in the Milky Way, whether giant planets naturally form at large distances from their hosts, extending the search for supermassive black holes and the search for alien technosignatures.

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 discuss the claimed detection of a starless dark matter subhalo, speedy, puffy white dwarfs, super massive black holes and how to form and grow them, smaller black holes and how to merge them, and star clusters in the Sparkler galaxy. Listen below, on Spotify, Apple podcasts or wherever you get your podcast.

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!
