223. Dark matter search prospects in gamma-ray astronomy: from the Galactic Center to external galaxies - [REMOTE] (TRANS/MWL/MM/DM)

Review

I review the arguments for interpretations of the Galactic Center gamma ray excess, the only significant detection to date of a possible indirect dark matter annihilation signal. I describe current search implications for complementary targets, most notably including nearby dwarf spheroidal galaxies, and the prospects for future improvements in gamma ray probes of DM.

Review

The launch of the Compton Gamma-Ray Observatory (CGRO) ushered in a new era in our understanding of the phenomenon of relativistic jets produced by compact objects. AGN with radio jets pointed towards us (blazars) turned out to be unexpectedly powerful and rapidly variable gamma-ray sources, while gamma-ray bursts were shown to be distributed isotropically on the sky, significantly increasing...
