Episode 7 - Black holes, stealthy satellites and the distance to DF2

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 to NGC1052-DF2 – Michael Beasley et al.Revisiting the globular clusters of NGC1052-DF2 – Katja Fahrion et al.Chemical signature reveals co-spatial dwarf satellite of an edge-on disc galaxy with MUSE – Devang Somawanshi et al.When Is a Bulge Not a Bulge?
