Welcome to the StarXiv! A monthly podcast that delves into the latest astronomy papers & results from the arXiv.
Hosted by Michelle, Payel, and Nicole.

Episode 44 – asteroid impacts, chemical evolution and quasi-stars
In this week’s episode, Michelle and NEWLY MINTED PhD, Dr Nicole, discuss papers including predictions for 10-metre plus asteroid impact rates on Earth and other planets, the abundance of life-critical Phosphorus in Galactic stars, age dating giants with the carbon-to-Nitrogen ratio and whether quasi-stars can explain the properties of little red dots! Tune in below,…

Episode 43 – early dark energy, the fate of Venusian moons, and the power of forbidden lines
In this episode, Michelle and Payel discuss whether early dark energy impacts large-scale structures and explore the possibility of Venus having a moon. They review papers on forbidden line emissions and galaxy evolution, including studies on extremely metal-poor galaxies. Listen on various platforms.

Episode 12 – Signs of life, little red dots and the links between star clusters and high redshift galaxies
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…

Episode 11: Whirling planes, wandering black holes and alien supernovae
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…

Episode 10 – Mixing dark matter, surviving black holes and hunting for planets
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…
-
Episode 9 – slowing bars, growing black holes, pasta sauces and AI
In this episode, Payel and Michelle discuss how you can slow down a galaxy’s bar, scaling relations for black holes, whether we can use intracluster light to learn about dark matter, little red dots, AI cosmologists and pasta sauce for all your plotting needs! Check out our episode – and the papers that inspired it…
The Hosts
Payel Das & Michelle Collins 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. Nicole Buckley is a PhD student at the University of Surrey. She loves reading papers!
