Massive Primordial Black Holes
arXiv:1911.02382
Abstract
A review of the astronomical data of several last years on an astonishingly high amount of black holes in the contemporary and early () universe is presented. Also the data on the recently observed peculiar stars in the Galaxy are discussed. It is argued that practically all black holes in the universe are primordial (PBH) and suggested that an inverted picture of the galaxy formation is realized: supermassive black holes were formed prior to galaxy formation and subsequently seeded the latter. Possibilities of cosmological dark matter consisting of primordial black holes and of abundant cosmological antimatter are considered. A mechanism of 1993 anticipating all these phenomena and predicting an extended log-normal mass spectrum of PBH is described.
