Statistics for dark matter subhalo searches in gamma rays from a kinematically constrained population model: Fermi-LAT-like telescopes

Understand

Cold dark matter subhalos are expected to populate galaxies in numbers.

• If dark matter self-annihilates, these objects turn into prime targets for indirect searches, in particular with gamma-ray telescopes.
• Incidentally, the Fermi-LAT catalog already contains many unidentified sources that might be associated with subhalos.
• In this paper, we determine the probability for subhalos to be identified as gamma-ray pointlike sources from their predicted distribution properties.
