Acerca de esta escucha

Hello! Welcome to the StarXiv, hosted by Dr Michelle Collins and Dr Payel Das. This is a biweekkly podcast that delves into the latest astronomy papers & results from the arXiv. Michelle and Payel are astronomers at the University of Surrey. They love research, but struggle to find time to read a lot of papers. They’re hoping this podcast fixes that. The beautiful logo is designed by Izzy Gray, a PhD student currently studying at the University of Surrey.

  • Episode 12 - Signs of life, little red dots and the links between star clusters and high redshift galaxies
    May 25 2025

    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. Listen below, on Spotify, Apple podcasts or wherever you get your podcasts!

  • Episode 11 - Whirling planes, wandering black holes and alien supernovae
    May 12 2025

    In this episode, Michelle and Payel discuss whether wandering intermediate black holes are mythical or not, how planes of satellites may form from cosmic accretion, how to form double hot Jupiters, whether Kelper's supernova remnant is an 'alien', whether Unions I is the faintest star cluster or the faintest galaxy, and just how old our globular clusters are. Listen below or check us out on Spotify, Apple Podcasts, or wherever you get your podcasts.

    Apr 28 2025

    This episode, Michelle and Payel delve into the latest constraints on mixed dark matter from the Lyman alpha forest, what happens to stars that get a little too close to a black hole, how machine learning can help identify stars likely to host an Earth-like planet, studying the dark ages from the Moon and witnessing the birth of nuclear star clusters!
