Primordial Kerr Black Holes

Presented by Dr. Alexandre ARBEY on 4 Jul 2019 from 15:10 to 15:30
Type: oral presentation
Track: Cosmological Probes


Primordial Black Holes (PBHs) are appealing candidates for dark matter in the universe but are severely constrained by theoretical and observational constraints. I will focus on the Hawking evaporation limits extended to Kerr Black Holes. These results have been obtained with a new code entitled BlackHawk that I will briefly present. In particular, I will review the isotropic extragalactic gamma ray background constraint and show that the "window" in which PBHs can constitute all of the dark matter depends strongly on the PBH spin. Finally, I will present a way to distinguish Black Holes of primordial origin from PBHs based on the Thorne limit on their spin.
