“Sterile” neutrinos are not sterile by virtue of their vacuum mixing with active neutrinos Gives effective interaction strength of the sterile neutrino relative to the Weak Interaction standard Weak Interaction It is by virtue of these tiny interactions that sterile neutrinos can be produced in the early universe or in supernovae
A heavy “sterile” neutrino can decay into a light “active” neutrino and a photon. The final state light neutrino and the photon equally share the rest mass energy of the initial heavy neutrino.
