| Abstract : | Despite a number of clear cosmological and astrophysical evidences for the presence of huge dark matter in the Universe, its basic constituents and nature still remain a riddle. Weakly Interacting Massive Particles (WIMPs) are among the many potential candidates proposed for dark matter. Indirect search experiments are carried out in astrophysics to probe the properties of WIMPs abundant in the Galactic Center and Dwarf Galaxies as they are supposed to capture the dark matter particles gravitationally. The interaction between WIMPs can lead to the production of standard model particles including the gamma-ray photons via self annihilation or decay. Search of the high energy gamma-ray signal originating from the Galactic Center and spheroidal dwarf galaxies can be used to constrain the parameter space for WIMP interactions. In this work, we present results from a Monte-Carlo simulation-based methodology developed for preparation of a source catalogue for MACE observations to search for the gamma-ray signal from spheroidal dwarf galaxies. We estimate the integral gamma-ray flux produced in the interactions of WIMPs in the mass range of 200 GeV to 5 TeV for different density profiles of dark matter. A catalogue of potential sources is prepared on the basis of their visibility at low zenith angles from the MACE site as well as higher integral flux level in the gamma-ray energy range above 20 GeV. We also discuss the plausible implications of the results expected from the search of dark matter from a sample of spheroidal dwarf galaxies using the MACE telescope. |
