We calculate the probability distribution function (PDF) of the expected annihilation luminosities of dark matter subhalos as a function of subhalo mass and distance from the Galactic center using a semianalytical model of halo evolution. We find that the PDF of luminosities is relatively broad, exhibiting a spread of as much as an order of magnitude at fixed subhalo mass and halo-centric distance. The luminosity PDF allows for simple construction of mock samples of {gamma}-ray luminous… Expand

Constraining Dark Matter Microphysics with the Annihilation Signal from Subhalos
In the cold dark matter scenario, galactic dark matter halos are populated with a large number of smaller subhalos. Previous work has shown that dark matter annihilations in subhalos can generate aExpand
Dark matter substructure modelling and sensitivity of the Cherenkov Telescope Array to Galactic dark halos
Hierarchical structure formation leads to a clumpy distribution of dark matter in the Milky Way. These clumps are possible targets to search for dark matter annihilation with present and futureExpand
Constraining the physics of galaxy formation and evolution using galaxy clustering
We model the evolution of galaxy clustering through cosmic time to investigate the nature of the power-law shape of ξ(r), the galaxy two-point correlation function. While ξ(r) on large scales is setExpand
We explore the halo-to-halo variation of dark matter (DM) substructure in galaxy-sized DM halos, focusing on its implications for strongly gravitational lensed systems. We find that the median valueExpand
Bailing out the Milky Way: variation in the properties of massive dwarfs among galaxy-sized systems
Recent kinematical constraints on the internal densities of the Milky Way's dwarf satellites have revealed a discrepancy with the subhalo populations of simulated Galaxy-scale halos in the standardExpand
Harnessing the Population Statistics of Subhalos to Search for Annihilating Dark Matter
The Milky Way’s dark matter halo is expected to host numerous low-mass subhalos with no detectable associated stellar component. Such subhalos are invisible unless their dark matter annihilates toExpand
Structure formation models weaken limits on WIMP dark matter from dwarf spheroidal galaxies
Dwarf spheroidal galaxies that form in halo substructures provide stringent constraints on dark matter annihilation. Many ultrafaint dwarfs discovered with modern surveys contribute significantly toExpand
