Pieri (lidia@physto.se), swe-pieri-L-abs1-og21-oralRecent numerical experiments have shown that a large fraction of the dark mass in our Galactic halo is notsmoothly distributed but is condensed in virialized dark substructures as light as 	 . In this work weestimate the  -ray flux expected from dark matter annihilation occurring within these minihalos, under thehypothesis that the bulk of dark matter is composed by neutralinos. We generated mock sky maps show-ing the angular distribution of the expected gamma-ray signal and assess its detectability with satellite-borneexperiments such as GLAST.
