Cosmological prior for the $J$-factor estimation of dwarf spheroidal galaxies

|
By Kavli IPMU, Kohei Hayashi, Sendai College, Shun’ichi Horigome
| Physical Review B
Dark matter halos of dwarf spheroidal galaxies (dSphs) play important roles in dark matter detection. Generally we estimate the halo profile using a kinematical equation of dSphs but the halo profile has a large uncertainty because we have only a limited number of kinematical datasets. In this paper, we utilize cosmological models of dark matter subhalos to obtain better constraints on halo profile of dSphs.
