-factor estimation of Draco, Sculptor and Ursa Minor dwarf spheroidal galaxies with the member/foreground mixture model
Shun-ichi Horigome, Kohei Hayashi, Masahiro Ibe +3
Dwarf spheroidal galaxies (dSphs) are promising targets of indirect detection experiments searching for dark matter (DM) at present universe. Toward robust prediction for the amoun…
Foreground effect on the -factor estimation of ultra-faint dwarf spheroidal galaxies
Koji Ichikawa, Shun-ichi Horigome, Miho N. Ishigaki +4
Dwarf spheroidal galaxies (dSphs) are promising targets for the gamma-ray dark matter (DM) search. In particular, DM annihilation signal is expected to be strong in some of the rec…
Foreground effect on the -factor estimation of classical dwarf spheroidal galaxies
Koji Ichikawa, Miho N. Ishigaki, Shigeki Matsumoto +4
The gamma-ray observation of the dwarf spheroidal galaxies (dSphs) is a promising approach to search for the dark matter annihilation (or decay) signal. The dSphs are the nearby sa…
Dark matter annihilation and decay from non-spherical dark halos in the Galactic dwarf satellites
Kohei Hayashi, Koji Ichikawa, Shigeki Matsumoto +3
The dwarf spheroidal galaxies (dSphs) in the Milky Way are the primary targets in the indirect searches for particle dark matter. To set robust constraints on candidate of dark mat…
