Description

I summarize recent constraints on dark matter candidate particles that produce X-ray emission lines, with an emphasis on the sterile neutrino. This includes a discussion of the candidate dark matter feature at ~3.55 keV discovered by stacking XMM-Newton spectrum of 73 galaxy clusters — a method that minimizes statistical and systematic uncertainties. The implications for identifying the dark matter particle and for physics beyond the Standard Model are discussed. I also indicate the uncertainties and caveats that remain with respect to the significance of the line and its interpretation as originating from dark matter decay. I look forward to future work that can narrow down the possible interpretations.
