Description
I present a novel mechanism for creating primordial black holes and dark MACHOs. A heavy dissipative dark sector can come to dominate the universe, creating an early matter dominated era prior to Big Bang Nucleosynthesis (BBN). At this time the dark matter can form halos which persist after the phase transition back to radiation domination, and slowly collapse at late times. This leads to the late time formation of dark MACHOs and subsolar mass primordial black holes. A possible consequence of this model is the present day high temperature evaporation of primordial black holes.
