Precise constraints on the dark matter content of Milky Way dwarf galaxies for gamma-ray experiments
Louis E. Strigari, Savvas M. Koushiappas, James S. Bullock +1
We examine the prospects for detecting gamma-rays from dark matter annihilation in the six most promising dwarf spheroidal (dSph) satellite galaxies of the Milky Way. We use recent…
Limits on the Radiative Decay of Sterile Neutrino Dark Matter from the Unresolved Cosmic and Soft X-ray Backgrounds
Kevork N. Abazajian, Maxim Markevitch, Savvas M. Koushiappas +1
We present upper limits on line emission in the Cosmic X-ray background (CXB) that would be produced by decay of sterile neutrino dark matter. We employ the spectra of the unresolv…
Proper motion of gamma-rays from microhalo sources
Savvas M. Koushiappas
I discuss the prospects of detecting the smallest dark matter bound structures present in the Milky Way by searching for the proper motion of -ray sources in the upcoming GLAST…
Constraints on Sterile Neutrino Dark Matter
Kevork Abazajian, Savvas M. Koushiappas
We present a comprehensive analysis of constraints on the sterile neutrino as a dark matter candidate. The minimal production scenario with a standard thermal history and negligibl…
