摘要: We present quantitative predictions for the detectability of individual Galactic dark matter subhalos in gamma-rays from pair annihilations their centers. Our method is based on a hybrid approach, employing highest resolution numerical simulations available (including recently completed one billion particle Via Lactea II simulation) as well analytical models extrapolation beyond simulations' limit. include self-consistent treatment subhalo boost factors, motivated by our results, and realistic expected backgrounds that must outshine. show reasonable values physics parameters (M_X ~ 50 - 500 GeV 10^-26 10^-25 cm^3/s) GLAST may very discover few, even up to several dozen, such subhalos, at 5 sigma significance, some more than 20 sigma. predict majority luminous sources would be resolved with GLAST's angular resolution. For most observer locations distribution detectable consistent uniform across sky. The brightest tend massive (median Vmax 24 km/s) therefore likely hosts dwarf galaxies, but many low km/s are also visible. Typically 40 kpc observer, only small fraction closer 10 kpc. total number observable has not yet converged simulations, we estimate missing 3/4 all subhalos.
