Attenuation of the ultra-high-energy neutrino flux by dark matter scatterings
Ivan Esteban, Alejandro Ibarra
A flux of ultra-high-energy (UHE) neutrinos, produced by astrophysical sources at cosmological distances, is anticipated to exist and reach Earth. In this paper, we investigate the…

Origin of cosmological neutrino mass bounds: background perturbations
Toni Bertólez-Martínez, Ivan Esteban, Rasmi Hajjar +2
The cosmological upper bound on the total neutrino mass is the dominant limit on this fundamental parameter. Recent observations-soon to be improved-have strongly tightened it, app…
