We summarize the impact of sterile neutrino dark matter on core-collapse supernova explosions. We explore various oscillations between electron neutrinos or mixed $\mu-\tau$ neutrinos and right-handed sterile neutrinos that may occur within a core-collapse supernova. In particular, we consider sterile neutrino masses and mixing angles that are consistent with sterile neutrino dark matter candidates as indicated by recent X-ray flux measurements. We find that the interpretation of the observed 3… Expand

Tau lepton asymmetry by sterile neutrino emission—moving beyond one-zone supernova models
The mixing of active neutrinos with their sterile counterparts with keV mass is known to have a potentially major impact on the energy loss from the supernova core. By relying on a set of threeExpand

Self-interacting sterile neutrino dark matter: The heavy-mediator case
For active-sterile mixing to be responsible for the full relic abundance of dark matter additional new physics is needed beyond the keV-scale sterile neutrino itself. The extra ingredient we considerExpand

In this paper we derive constraints on the emission of a massive (pseudo)scalar $S$ from annihilation of neutrinos in the core of supernovae through the dimension-4 coupling $\nu\nu S$, as well asExpand
Interpreting the Reactor Anomaly of Neutrino Data in Models with Sterile Neutrinos
Abstract A possible interpretation of the reactor antineutrino anomaly as an effect of one or three sterile neutrinos is discussed. The asymmetry of the probability of muon (anti)neutrino–electronExpand
SO(10) model of standard and dark matter
We consider a novel model for three standard families of left chiral states of quarks and leptons conjointly with a new family of dark matter fermionic particles and a sterile neutrino. It isExpand
