Cosmic Rays from Heavy Dark Matter from the Galactic Center
Jose A. R. Cembranos, Viviana Gammaldi, Antonio L. Maroto
The gamma-ray fluxes observed by the High Energy Stereoscopic System (HESS) from the J1745-290 Galactic Center source is well fitted by the secondary photons coming from Dark Matte…
Reliability of Monte Carlo event generators for gamma ray dark matter searches
J. A. R. Cembranos, A. de la Cruz-Dombriz, V. Gammaldi +2
We study the differences in the gamma ray spectra simulated by four Monte Carlo event generator packages developed in particle physics. Two different versions of PYTHIA and two of…
Spectral Study of the HESS J1745-290 Gamma-Ray Source as Dark Matter Signal
J. A. R. Cembranos, V. Gammaldi, A. L. Maroto
We study the main spectral features of the gamma-ray fluxes observed by the High Energy Stereoscopic System (HESS) from the J1745-290 Galactic Center source during the years 2004,…
