50. Spatial signature of Dark Matter in the Galaxy

Francesca Calore (University of Amsterdam)

A generic prediction of simulations of structures formation is the presence in our Galaxy of a population of dark matter subhaloes, hosted by the main dark matter halo. The annihilation of dark matter particles in those objects may lead to the production of gamma rays, inducing small scale fluctuations in the gamma-ray diffuse emission. In order to understand the origin and the composition of...

51. Correlated statistical noise in power spectrum measurements

Sheldon Campbell (The Ohio State University)

Observations of cosmic gamma-ray or neutrino events is a Poisson point process on the sphere with 2D spatial correlations sourced by the skymap of astronomical sources. With this perspective, the statistical distribution of the power spectrum of observed events can be expressed exactly, depending only on the number of events N and the angular flux distribution of sources. This talk explores...

52. Probing WIMP Dark Matter with gamma rays and over 1000 deg^2 of weak lensing data

Tilman Troester (University of British Columbia)

Weakly interacting massive particle (WIMP) dark matter has a small but non-zero interaction cross-section with standard model physics. Gamma-rays from dark matter annihilations could then be observable by gamma-ray telescopes such as Fermi-LAT and used to constrain the annihilation cross-section. Cross-correlation of gamma-rays with tracers of dark matter improves the sensitivity and avoids...
