Weakly interacting massive particles (WIMPs) are the most interesting cold dark matter candidates produced in the early Universe. It is believed that Dwarf spheroidal galaxies are the best location to search DM.These are known as most dark matter dominated objects.Dark matter can be searched in these locations by WIMPs annihilation into high energy radiation. Here we have assumed neutarlino as WIMP. In our study we consider Draco and Ursa minor galaxy. For all dSph DM density profile is considered to be same. NFW density profile is considered . In this paper we have estimated the luminosity of dSph by annihilation of neutralino (WIMPs). |
