James Webb Space Telescope: data, problems, and resolution

TL;DR

This paper discusses how primordial black holes could explain certain astronomical observations and resolve issues with the standard big bang cosmology, suggesting they may constitute all dark matter and influence galaxy formation.

Contribution

It revisits and supports the primordial black hole seed model for galaxy formation, aligning it with recent data and expanding its implications for dark matter and antimatter presence.

Findings

PBH mass spectrum matches astronomical data

Predicted PBH abundance could account for all dark matter

Data suggests antimatter presence in the Milky Way

Abstract

It is argued that the data presented by Hubble Space Telescope and James Webb Space Telescope, that seem to be at odds with the canonical big bang cosmology, find simple explanation if galaxy formation is seeded by massive primordial black holes (PBH), as anticipated in 1993 (A. Dolgov and J. Silk, later DS). The statement that the galaxy formation might be seeded by PBH is now rediscovered in several works. The predicted by DS log-normal mass spectrum of PBHs very well agrees with astronomical data. Abundant BH population of the Galaxy with masses of the order of tens solar masses is predicted. Extended mass spectrum of PBH together with their possible clustering allows them to make 100\% contribution into the cosmological dark matter. Another prediction of DS mechanism on noticeable amount of antimatter in the Milky Way also seems to be confirmed by the data.
