Solution of JWST and HST problems by primordial black holes

Understand

Observations of the early universe at redshifts of order 10, collected during the last several years presented by the Hubble Space Telescope (HST) and recent data by the James Webb Space telescope (JWST) created strong doubts on the validity of the conventional $\Lambda$CDM cosmology.

• It is argued here that the 30 year old conjecture by A.Dolgov \& J.Silk~\cite{DS} of galaxy and quasar seeding by supermassive primordial black holes (SMBHs) naturally solves the problem of the observed dense early population of the universe, as well as the problem of the formation of SMBH in the contemporary universe.
• The idea of seeding of cosmic structures by SMBH is supported by a good agreement of the predicted log-normal mass spectrum of primordial black holes (PBH) with observations and by a noticeable antimatter population of the Milky Way.
