Morning session (2)

In the recent past, statistical image analysis techniques have been proven to provide unprecedented sensitivity for decomposing gamma-ray sky maps. In this talk, I will use statistical properties (the 1-point PDF) of the Fermi-LAT photon counts map to measure the composition of the gamma-ray sky at high latitudes. I will introduce a new method, generalizing the use of standard pixel-count...

The one-point function (i.e., the isotropic flux distribution) is a complementary method to (anisotropic) two-point correlations. Using analytical models of structure formation and dark matter halo properties, we compute the gamma-ray flux distribution due to annihilations in extragalactic dark matter halos, and relate this to indirect DM searches with Fermi Large Area Telescope. Using...

48. Tomography of the Fermi-LAT diffuse extragalactic signal via cross-correlation with galaxy catalogues
Alessandro Cuoco (U)
Maciej Bilicki (Leiden University)
Various cosmological studies require wide-angle galaxy catalogs with 3-dimensional information on source positions. Such datasets, when covering a significant fraction of the sky, are particularly useful for cross-correlation techniques allowing to detect signals buried under the noise in auto-correlations. I will present two recently compiled photometric redshift catalogs covering most of the...
