Episode 23 – Failed galaxies, faint galaxies, and the proto-Galaxy
In this episode, Michelle and Nicole explore the chemistry of faint galaxies and RR-Lyrae stars, tracing the proto-Galaxy, discussing the failure of some galaxies, examining quasi-stars in relation to Little Red Dots, and discussing whether UNIONS 1 is a galaxy or a star cluster. Listen on major podcast platforms.

Episode 22 – ORCs, rings, and Galactic histories
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…

Episode 21 – Mercury, chemistry and quasi periodic eruptions

In this episode, Michelle and Nicole explore various astronomical topics, including merger debris around a galaxy, metal-mixing in early stars, quasi-periodic eruptions in Ansky, relic galaxies, Mercury’s magnetosphere, and second-generation stars in globular clusters. Tune in on Spotify, Apple Podcasts, or other platforms for more insights.

Episode 19 – Peering into the Local Universe, distant black holes, forming planets and alien signatures
In this episode, Michelle and Payel explore the chemistry of nearby M-dwarf stars and the formation of giant planets at significant distances from their hosts. They discuss supermassive black holes and the search for alien technosignatures. Relevant research papers discussed are also highlighted for further reading.

Episode 18 – disks, disks and more disks!
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…
