Description
In order for gas clouds in the early universe to undergo direct collapse, cooling via H2 must be suppressed. We are exploring the effect of the Hawking radiation from small PBHs by computing the expected photon spectrum from black hole evaporation and its effect on supporting H2 suppression in a surrounding gas cloud. Our goal is to determine the density and mass distribution of PBHs needed to generate a photon flux in the low UV/Gamma range that would enable direct collapse of the gas cloud into a SMBH seed at redshifts consistent with the James Webb Space Telescope’s Little Red Dot observations.
