Neutrino Emission and Plasma Heating from Primordial Black Holes: An Improved Approach to $N_{eff}$ Constraints

Héctor Sanchis, Gabriela Barenboim, Yuber F. Perez-Gonzalez

We investigate the impact of neutrino emission via Hawking radiation from primordial black holes (PBHs) on the cosmological effective number of neutrino species, $N_{eff}$ …

A bound on thermal y-distortion of the cosmic neutrino background

Gabriela Barenboim, Héctor Sanchis, William H. Kinney +1

We consider the possibility that the cosmic neutrino background might have a nonthermal spectrum, and investigate its effect on cosmological parameters relative to standard $Λ$ -Col…
