Scientific paper

The EGRET telescope has found evidence for a γ-ray source at the Galactic center (GC). We investigate whether the spectral features of this source are compatible with the γ-ray flux induced by pair annihilations of dark matter weakly interacting massive particles (WIMPs). We show that the discrimination between this interpretation and other viable explanations will be possible with GLAST, the next major γ-ray telescope in space. On the other hand, we also show that if the data will point to an alternative explanation, there will still be the possibility for GLAST to single out a weaker dark matter source at the GC. The talk is entirely based on Cesarini et al. 2003.
