Astro Seminar

Primordial Black Holes: gravitational-wave signatures and possible contribution to the dark matter

Speaker: Sebastien Clesse (Brussels)
Date: Wednesday 10 March 2021
Time: 14:00
Venue: Zoom

The detection of gravitational-waves from binary black hole mergers has rekindled the idea that primordial black holes may have formed in the early Universe. I will review some recent developments in the field of primordial black holes: formation mechanisms, mass function, astrophysical limits, possible contribution to the Dark Matter and links to the Baryogenesis. I will particularly focus on their gravitational-wave signatures: merging rates, explanation of recent LIGO/Virgo events (GW190521, GW190815, GW190425), subsolar black hole searches, spin distribution, stochastic gravitational-wave backgrounds and continuous waves as a probe of planetary-mass primordial black holes.
