Cosmological constraints on sterile neutrinos |
Abstract _ |
Sterile neutrinos come in two kinds in the cosmological context. On one hand we have very weakly coupled sterile neutrinos with masses of the order of a few keV that act as a dark matter candidate. On the other hand people are also considering light and completelly thermalised neutrino species with masses of around 1eV or less. I will discuss how cosmology can constrain both of these sterile neutrino candidates, what are the present limits and possible work-arounds. |
