Primordial Black Holes Around Us Now, Long Before, and Far away
arXiv:2010.11824 · doi:10.1088/1742-6596/1690/1/012183
Abstract
Recent astronomical data on Black hole observations are reviewed. The arguments in favor that the observed black holes are predominantly primordial (PBH) are presented. The mass spectrum of PBH is best fit to the log-normal one. A model of PBH formation with log-normal spectrum is briefly described.
