SUMMARY:Sterile Neutrinos as Dark Matter: From Production to Predictions
DESCRIPTION:Sterile neutrinos with masses of a few keV are very\nwell-motivated Dark Matter candidates. However\, even though they have the\nperfect properties for that job\, it is unclear how to produce them in the\nearly Universe. In this talk\, I will mainly focus on how to make this\nproduction happen in the early Universe. While several proposals exist in\nthe literature\, the production aspect unfortunately suffers from several\nincorrect or at least oversimplified statements (e.g.\, that keV sterile\nneutrino Dark Matter would usually be ‘warm’). I will make an attempt to\nexplain parts of the issues and how to resolve them\, which ultimately\nleads to means to distinguish the different mechanisms via their impact on\ncosmic structure formation. While lab experiments are not well-suited to\nprobe this type of Dark Matter candidate\, cosmology and astrophysics\nprovide the tools to do so. The whole talk is supposed to be more\npedagogical than technical\, so I will avoid heavy formula whereever\npossible.
