Primordial Black Holes as Dark Matter: The Power Spectrum and Evaporation of Early Structures
Year: 2003
Type: article
Abstract: We consider the possibility that massive primordial black holes are the dominant form of dark matter. Black hole formation adds a Poisson noise to the matter density fluctuations. We use Lyα forest observations to constrain this Poisson term, which constrains the black hole masses to be less than approximately a few times 10 4 M ☉ . We also find that structures with less than ~10 3 black holes evaporate by now.
