Cosmic objects with magnetic fields (quasars, AGNs) are observed at redshifts z≥7 and more (for instance, for z=10.073±0.002) indicates the early creation of magnetic fields. The observations of the cosmic telescope JWST show that the first galaxies were formed at redshifts z$\simeq$15 - 20. The early formation of galaxies creates favourable conditions for high impact of the Compton...
Brief overview and new results
We show that Compton scattering by electrons of the hot intergalactic gas in galaxy clusters should lead to peculiar distortions of the cosmic background X-ray and soft gamma-ray radiation - an increase in its brightness at energies smaller than 60-100 keV and a drop at higher energies. In the cluster frame the maximum of the background decrease occurs at ~500-600 keV due to the recoil effect....
