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 7: black holes, stealthy satellites and the distance to DF2
In this episode of The Starxiv, Michelle and Payel discuss a revised distance for the controversial ultra-diffuse galaxy, DF2; a discovery of a supermassive black hole in an ultra compact dwarf; 2 galaxies hiding in plain sight; and how statistical mechanics may help with dark matters cusp-core problem. Michelle and Payel also have to put…
