In this episode, Michelle and Nicole discuss what sets the chemistry of the faintest galaxies and RR-Lyrae stars, how to trace the proto-Galaxy, why some galaxies fail to thrive, can quasi-stars can explain Little Red Dots, and whether UNIONS 1 is a galaxy or a star cluster. Tune in below, on Spotify, Apple or wherever you get your podcasts.
