"We entertain the possibility that primordial black holes of mass ∼(1024−1026) g, with sub-millimeter Schwarzschild radii, constitute all or a significant fraction of cosmic dark matter, as allowed by various constraints. In case such primordial black holes get captured in orbits around neutron stars or astrophysical black holes in our galactic neighborhood, gravitational waves from the resulting "David & Goliath" binaries could be detectable at Advanced LIGO or Advanced Virgo from days to years, for a range of possible parameters. The proposed Einstein Telescope would further expand the reach for dark matter primordial black holes in this search mode."
