200. Exotic needles in the Cherenkov telescopes haystack

Michele Doro (PD)

6/22/16, 5:20 PM

Ground-based Imaging Cherenkov Telescopes observed the Cherenkov radiation emitted in extended atmospheric showers generated by cosmic gamma rays in the TeV regime. The rate of these events is normally overwhelmed by many orders of magnitude larger triggers from cosmic rays induced showers. A large fraction of these "background" events is vetoed at the on-line trigger level, but a substantial...

56. Search for annihilating Dark Matter towards dwarf galaxies by the Cherenkov Telescope Array

Gonzalo Rodriguez Fernandez (ROMA2)

The standard model of cosmology indicates that approximately 27% of the energy density of the universe is in the form of dark matter. The nature of dark matter is an open question in modern physics. The concordance cosmological model ($\Lambda$CDM) suggests a non-baryonic dark matter compatible with a gas of cold and weakly interacting massive particles (WIMPs). Indirect dark matter searches...

199. New measurement of the angular power spectrum of anisotropies in the data of Fermi-LAT

Mr Mattia Fornasa (School of Physics and Astronomy of the University of Nottingham)

6/22/16, 6:30 PM

The Diffuse Gamma-Ray Background (DGRB) collects the radiation produced by all those sources that are not bright enough to be resolved individually. Therefore, it represents an essential tool to study faint gamma-ray emitters, like star-forming or radio galaxies and the exotic Dark Matter. The anisotropy pattern of the DGRB is extremely informative: I will review the recent measurement of the...

198. Particle dark matter signals in the anisotropic sky: a cross-correlations approach

Marco Regis (TO)

6/22/16, 6:55 PM

Anisotropies in the electromagnetic emission induced by dark matter (DM) annihilation or decay in the extragalactic sky are a recent tool in the quest for a particle DM evidence. In this talk, I will review on-going searches involving the two-point angular cross-correlation signal between the multi-wavelength emission from WIMP DM and gravitational tracers of the DM distribution in the...

284. On Fermi-LAT, H.E.S.S. and the Cherenkov Array Telescope Sensitivity to Dark Matter Annihilation

Dr Farinaldo Queiroz (Max Planck Institute for Nuclear Physics - Heidelberg)

6/22/16, 7:20 PM

I discuss how one can extend Fermi-LAT and H.E.S.S. limits on gamma-ray lines from dark matter annihilation to energies larger than currently accessible. Moreover, I present Fermi-LAT, H.E.S.S. and the Cherenkov Array Telescope sensitivity to neutrino signals and show that we have already entered into a new era where gamma-ray telescopes are more sensitive than neutrino detectors to neutrino...
