Mixed Sterile Neutrino Dark Matter and Small Scale Structure Formation

Dark matter is abundant within our universe, yet its origins and exact nature remains unknown. CMB and large scale structure observations constrain the total quantity and distribution of dark matter, and a possibly anomalous 3.55 keV X-Ray line could have dark matter origins. These constraints allow us to probe the properties of dark matter and the means of their production. In this poster, we explore production mechanisms for sterile neutrino dark matter that may be consistent with dark matter interpretations of the X-Ray line and large scale structure constraints.
