Primordial black holes in the dark matter Galactic halo

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.
