  We have explored the impact of sterile neutrino dark matter on core-collapse
supernova explosions. We have included oscillations between electron neutrinos
or mixed $\mu,\tau$ neutrinos and right-handed sterile neutrinos into a
supernova model. We have chosen sterile neutrino masses and mixing angles that
are consistent with sterile neutrino dark matter candidates as indicated by
recent x-ray flux measurements. Using these simulations, we have explored the
impact of sterile neutrinos on the core bounce and shock reheating. We find
that, for ranges of sterile neutrino mass and mixing angle consistent with most
dark matter constraints, the shock energy can be significantly enhanced and
even a model that does not explode can be made to explode. In addition, we have
found that the presence of a sterile neutrino may lead to detectable changes in
the observed neutrino luminosities.
