DM search in dwarf spheroidal galaxies

アブストラクト：
The nature of dark matter (DM) is still a big mystery. Among the varieties
of candidates, Weakly Interacting Massive Particle (WIMP) is one of the
most promising ones. Gamma-ray observations of dwarf spheroidal galaxies
(dSphs) by Fermi satellites put the strongest constraints at mDM~ < a few
hundreds of GeV. In the near future, Cherenkov Telescope Array (CTA) starts
its operations and expect to probe WIMP of mDM > ~O(1)TeV. Different from
previous experiments, spatial distributions of DM in dSphs are resolved
with CTA. In this talk, I explain the procedure to extract DM signals in
gamma-ray observations and how the spatial extension of the dSph affects
our accessibility to DM in future experiments.
