 Primordial black holes as dark matter candidate are severely constrained by the Galactic Center 511 keV gamma-ray line / Laha, Ranjan We derive the strongest constraint on the fraction of dark matter that can be composed of low mass primordial black holes by using the observation of the Galactic Center 511 keV gamma-ray line.
