Primordial black holes are black holes that may have formed in the early Universe. Their masses potentially span a range from as low as the Planck mass up to many orders of magnitude above the solar mass. This, in particular, includes those black holes recently discovered by LIGO/Virgo, and these may conceivably be of primordial origin. Furthermore, there are now numerous recent hints for compact bodies constituting (part of) the dark matter. After a general introduction of the topic, I will talk about those, their connection and future detection possibilities.
Dr. Florian Kühnel is researcher at the Max Planck Institute for Physics, located near Munich, Germany. He is best known for his work on primordial black holes, where he authored numerous paper, including some of the most-cited articles. He is also working on quantum effects of black holes, and together with Gia Dvali and Michael Zantedeschi has recently found the novel quantum characteristic of vorticity in black holes. Prior to this, he worked on modified gravity, inflation and condensed-matter physics, and their interplay. His previous affiliations include Ludwig Maximilian University of Munich and Ecole Normale Superieure in Paris.
