DM clumps as discrete sources of gamma-radiation
  Massive objects (clumps) of Cold Dark Matter (CDM) in Galaxy can appear due to its annihilation as discrete sources of gamma-radiation. Some number of unidentified regular gamma-sources, observed by EGRET, can be accounted for by massive CDM clumps. Future gamma-ray expreriment GLAST in combination with data of EGRET will enable to probe a wide range of models of clumped annihilating CDM.
