This episode, Michelle is back and she and Payel discuss long period pulsars, population III galaxies, latent variables in Galactic archaeology, accreted globular clusters, planets that cause their star to flare and avoiding photo0z catastrophes.

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.
