Abstract
If dark matter interacts with the Standard Model only gravitationally its abundance in the universe could be explained by the evaporation of primordial black holes (PBH) through Hawking radiation which ``democratically'' emits all existing particles. In these two papers, the authors study this scenario in great detail, significantly improving on previous calculations, and eventually include also interactions with the Standard Model. One curious observation is the strong dependence of the necessary density of PBH on the spin of the dark matter particles.
