Primordial black holes in the dark matter halo of our Galaxy
Prof. Marek AbramowiczCambridge Fluids Network - fluids-related seminars19 March 2024 2:00pmThe 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.
