Heavy sterile neutrino emission in core-collapse supernovae: Constraints and signatures

Leonardo Mastrototaro, Alessandro Mirizzi, Pasquale Dario Serpico +1

Heavy sterile neutrinos with masses $\mathcal{O}(100)$ MeV mixing with active neutrinos can be produced in the core of a collapsing supernova (SN). In order to avoid an excessive…
