Primordial black holes in the dark matter halo of our Galaxy

Prof. Marek Abramowicz Cambridge Fluids Network - fluids-related seminars 19 March 2024 2:00pm The Hoyle Lecture Theatre + Zoom If there are primordial black holes in the dark matter halo, they must collide with the Galactic neutron stars (NSs) and produce light black holes (LBHs), with masses below 1.4 M_Sun. This has observational consequences that may be checked by microlensing, by LIGO-Virgo-Kagra interferometers detecting gravitational waves from collisions of LBHs with NSs and BHs, and (possibly) by detecting LBHs in X-ray binaries and from pulsars statistics.
