Highlights on gamma rays, neutrinos and antiprotons from TeV Dark Matter
Viviana Gammaldi
It has been shown that the gamma-ray flux observed by HESS from the J1745-290 Galactic Center source is well fitted as the secondary gamma-rays photons generated from Dark Matter a…
Antiproton signatures from astrophysical and dark matter sources at the galactic center
J. A. R. Cembranos, V. Gammaldi, A. L. Maroto
The center of our Galaxy is a complex region characterized by extreme phenomena. The presence of the supermassive Sagittarius A* black hole, a high Dark Matter density and an even…
Neutrino fluxes from Dark Matter in the HESS J1745-290 source at the Galactic Center
J. A. R. Cembranos, V. Gammaldi, A. L. Maroto
The spectral study of the HESS J1745-290 high energy gamma-ray cut-off from the galactic center is compatible with a signal of Dark Matter (DM) annihilation or decay. If this is th…
Gamma-ray and neutrino fluxes from Heavy Dark Matter in the Galactic Center
V. Gammaldi, J. A. R. Cembranos, A. de la Cruz-Dombriz +2
We present a study of the Galactic Center region as a possible source of both secondary gamma-ray and neutrino fluxes from annihilating dark matter. We have studied the gamma-ray f…
