Talk Sterile neutrinos as dark matter Session 9

Speaker

Prof. Kevork N. Abazajian

Description

I will review the variety of dark matter production models for sterile neutrino dark matter and their connection to structure formation and X-ray line detection, including the candidate 3.5 keV line. Structure formation continues to constrain dark matter to be increasingly cold, yet puzzles remain in galactic substructure. A few searches have claimed constraints on the presence of a dark matter source for the 3.5 keV line, yet the 3.5 keV continues been seen in a large number of sources on the sky. New technologies must come on line for a definitive experimental result.
