Description
Summary:(GLAST LAT Collaboration) We study the prospects for detecting gamma-rays from point sources of Dark Matter annihilation with the space satellite GLAST. We apply the obtained results to the so-called mini-spikes scenario, where the annihilation signal originates from large Dark Matter overdensities around Intermediate Mass Black Holes. We find that if these objects exist in the Galaxy, not only GLAST should be able to detect them over a timescale as short as 2 months, but in many cases it should be possible to determine with good accuracy the mass of the annihilating Dark Matter particles, while null searches would place stringent constraints on this scenario.
