Harvard ADS: Black Dark Matter and Antimatter

Paper abstract: It is shown that the dense population of the early universe with well developed galaxies and supermassive black holes (quasars), observed by HST and JWST, nicely fits the conjecture that the galaxies and quasars are seeded by primordial black holes (PBHs), proposed in our work more than 30 years ago. This idea of galaxy seeding by massive black holes is rediscovered in recent publications by several groups. The predicted log-normal mass spectrum of PBHs very well agrees with the observations. Our other prediction of noticeable amount of antimatter in the Galaxy is also confirmed by the data.
