In this episode, we had Payel and Nicole filling in for Michelle who’s away on holiday. Nicole is a PhD student, also at the University of Surrey Astrophysics research group. They discuss the direct detection of HI beyond the local universe, how the Milky Way seems unusually cold, a planetary system with two misaligned planets, detecting stars of common origin through the ratio of alpha elements produced through hydrostatic channels to those produced through explosive ones, twin collisional-ring galaxies, and the impact of the initial mass function on chemical evolution at high redshift.

Lonely Little Red Dots: Challenges to the AGN-nature of little red dots through their clustering and spectral energy distributions - María de las Mercedes Carranza Escudero

This episode, Michelle and Payel are very on-theme as they discuss whether Little Red Dots can be explained by super Eddington accretion; the high abundances of nitrogen to oxygen in the most distant galaxies and whether this is tied to globular cluster formation; the stellar graveyard in galaxies, and claims of signs of life in distant world.
