Cosmic Conundra explained by Primordial Black Holes?

The known thermal history of the Universe is expected to shape the mass function of primordial black holes. Sébastien, Bernard Carr, Juan García-Bellido and Florian Kühnel shed a new light on a series of unexplained cosmic conundra in Ref.[1].


This figure shows some expected mass fraction distributions of primordial black holes as dark matter and the limits imposed by various astrophysical probes.
