StarXiv: a podcast discussing the latest astronomy papers

Michelle and Payel

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.

Black holes, stealthy satellites and the distance to DF2

StarXiv: a podcast discussing the latest astronomy... ·

2025/03/10

In this episode of The Starxiv, Michelle and Payel discuss a revised distance for the controversial ultra-diffuse galaxy, DF2; a discovery of a supermassive black hole in an ultra compact dwarf; 2 galaxies hiding in plain sight; and how statistical mechanics may help with dark matter's cusp-core problem. Michelle and Payel also have to put up with slightly inferior audio quality as the undergraduates reclaimed their recording equipment!This episode's papers:A new way to measure the distance
