As the only dark matter candidate that does not invoke a new particle that survives to the present day, primordial black holes (PBHs) have drawn increasing attention recently. Up to now, various observations have strongly constrained most of the mass range for PBHs, leaving only small windows where PBHs could make up a substantial fraction of the dark matter. Here we revisit the PBH constraints for the asteroid-mass window, i.e., the mass range 3.5× 10−17M⊙ < mPBH < 4× 10−12M⊙. We revisit 3…

Constraints on primordial black holes

The constraints on the fraction of the Universe that may have gone into primordial black holes (PBHs) over the mass range 10−5 to 1050 g are updated and even if PBHs make a small contribution to the DM, they could play an important cosmological role and provide a unique probe of the early Universe.
