Unidentified sources in the Fermi-LAT second source catalog: the case for DM subhalos

Horns, Dieter; Zechlin, Hannes-S.

The Large Area Telescope (LAT) aboard the Fermi satellite allows us to study the high-energy γ-ray sky with unprecedented sensitivity. However, the origin of 31% of the detected γ-ray sources remains unknown. This population of unassociated γ-ray sources may contain new object classes, among them sources of photons from self-annihilating or decayi…
