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.
