Description

Hawking evaporation of primordial black holes (PBH) with masses ranging from ∼10^-1 to ∼10^9 g can generate the whole observed dark matter (DM) relic density. However, a second DM production mechanism, like freeze-out or freeze-in, could have also been active in the early universe. Here we study the interplay of these mechanisms, focusing on the scenario where PBHs dominate the energy density of the universe, leading to a nonstandard cosmological era.
