In early 2020, I gave a presentation in the public talk series Babelsberger Sternennächte of the Leibniz-Institute for Astrophysics, Potsdam (AIP). It was very well attended, but still only people in Potsdam could participate. Now that everything has moved online, I had the pleasure to record that talk, titled “Dark Matter and the Dance of Dwarf Galaxies”, for the new Virtual Babelsberger Sternennächte.
As of May 20, it is available online on YouTube, and I’ve also embedded it below.
