Fifty shades of grayness: parametrizations of spectral distortions and applications in cosmology
Gabriela Barenboim, Julien Froustey, Cyril Pitrou +1
Thermal distribution functions can only be of the Fermi-Dirac or Bose-Einstein types, whereas distorted spectra encompass any possible deviations from these shapes. It is fruitful…
Primordial neutrinos fade to gray: constraints from cosmological observables
Gabriela Barenboim, Julien Froustey, Cyril Pitrou +1
We investigate the effect of potentially large distortions of the relic neutrino spectra on cosmological observables. To that end, we consider a phenomenological model of "gray" sp…
Neutrino Emission and Plasma Heating from Primordial Black Holes: An Improved Approach to 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, …
