Description

Recent X-ray observations of galaxies and galaxy clusters suggest the existence of sterile neutrino dark matter with a mass of 7.1 keV. In this poster, we examine mixed dark matter models, comprised of both sterile neutrinos and cold dark matter, with sterile neutrino parameters consistent with the X-ray observations. We assess the compatibility of these models with observation by calculating cosmological observables resulting from sterile neutrino production mechanisms.
