Abstract/Summary: | |
This work focuses on models of galactic dark matter halos and observational prospects. We investigate the impact of careful computation of the phase-space density and velocity distribution of weakly-interacting massive particles, a major class of dark matter particle candidates, in the Milky Way. In particular, the possibility of a non-trivial velocity-dependence in the self-annihilation cross-section from the Sommerfeld effect is considered in indirect detection; we derive an upper limit on the local velocity dispersion and examine the significance of local anisotropy in the local dark matter distribution in direct detection efforts. |
