Dark matter substructure and gamma-ray annihilation in the Milky Way halo

We present initial results from "Via Lactea," the highest resolution simulation to date of Galactic CDM substructure. It follows the formation of a Milky Way-sized halo with M-halo = 1.8; 10(12) M-circle dot in a WMAP three-year cosmology, using 234 million particles. Over 10,000 subhalos can be identified at z = 0: their cumulative mass ...更多
