Description
If there are primordial black holes in the dark matter halo, they must collide with the Galactic neutron stars (NS) and produce light black holes (LBH), with masses below 1.4 M_Sun. This has observational consequences that may be checked by microlensing, by LIGO-Virgo-Kagra iterferometers detecting gravitational waves from collisions of LBH with NS and BH, by detecting LBH in X-ray binaries and from pulsars statistics. I will describe most recent developments in the subject, in particular the microlensing OGLE results.
