The nature of dark matter and the explosion mechanism of core-collapse supernovae may both be explained by the presence of a sterile neutrino. Observations of galaxies and galaxy clusters are indicative of a $\sim$keV mass sterile neutrino. Oscillations between an electron neutrino and a sterile neutrino in the $\sim$keV mass range may provide an efficient energy transport mechanism between the proto-neutron star and stalled shock wave. We have performed simulations of core-collapse supernovae for a range of sterile neutrino masses and mixing angles that are consistent with dark matter. We have found that, for many choices of mass and mixing angle, the presence of a sterile neutrino is sufficient to enhance the neutrino reheating and result in a successful explosion.
