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\times 10^{-17}M_\odot < m_{\mathrm{PBH}} < 4… ## Figures from this paper Navigating the asteroid field: New evaporation constraints for primordial black holes as dark matter Primordial black holes (PBHs) in the asteroid-mass range (10−17–10−12) M almost entirely escape constraints as dark matter candidates.
