Dark Matter Indirect Searches

Talk

Relativistic axion-like particles originating from the stellar interiors, along with the ones coming from axion-photon mixing in the galactic magnetic fields, contribute together to make an energetic component of the axion content of the galaxies. Considering an isotropic distribution of galaxies in the universe, these highly relativistic axions (Lorentz factor at least of the order 10^6)...

Dark Matter Indirect Searches

Talk

I will show how it is possible to place sound constraints on DM self annihilation cross sections by making use of cosmological observables. Current CMB measurements do in fact allow the possibility to test DM self-annihilation down to the thermal values for particle masses of few GeV, and to place constraints that depend only on cosmological parameters. This kind of constraints, competitive...

Dark Matter Indirect Searches

Talk

Satellite dwarf galaxies in the vicinity of the Milky Way are ideal candidates for the detection of dark matter annihilation signals. If the positron fraction and combined electron positron flux excesses recently observed by PAMELA and FERMI are due to dark matter annihilation, ground-based atmospheric cherenkov telescopes (ACTs) may be able to observe energetic gamma rays from the accompanying...

90. New Approaches in the Search for Solar WIMPs

Talk

The search for neutrinos from dark matter self annihilations in the Sun offer exciting ways to probe the WIMP-Proton scattering cross section. We discuss new approaches in the search for such signals and provide sensitivities for neutrino detectors.

101. Effects of WIMP DM transport in the Sun

Talk

We study the effects of transport and annihilations induced by WIMP DM over the Sun, focusing in particular on the possible reduction of the solar neutrino fluxes due to the energy carried away by wimps from the innermost regions of the Sun, and to the consequent reduction of the temperature of the Solar core. We find that for standard WIMPs, even in the very low-mass range between 4 and...
