Dark Matter Detections in Photons Split by a Million in Energy: Interpretations of X-ray lines and Gamma-ray Bumps
Kevork Abazajian, Professor, Dept of Physics & Astronomy, UC Irvine,

I will give an overview of the analyses leading to two recent candidate detections of photons from dark matter.  Specifically, these are: first, gamma rays in a continuum "bump" at a few GeV which can be due to WIMP-like dark matter annihilation in the Galactic Center; and, second, X-rays from clusters of galaxies and Andromeda consistent with monoenergetic photons from dark matter decay such as that predicted from sterile neutrino dark matter.  I will discuss the particle and cosmological model implications of both candidate signals.
