Dark Matter search in dwarf irregular galaxies with the Fermi Large Area Telescope
V. Gammaldi, J. Pérez-Romero, J. Coronado-Blázquez +4
We analyze 11 years of Fermi-LAT data corresponding to the sky regions of 7 dwarf irregular (dIrr) galaxies. DIrrs are dark matter (DM) dominated systems, proposed as interesting t…
Theoretical predictions for dark matter detection in dwarf irregular galaxies with gamma rays
V. Gammaldi, E. V. Karukes, P. Salucci
We investigate dwarf irregular(dIrr) galaxies as a new category of targets for indirect Dark Matter(DM) searches with gamma-rays. In the framework of point-like analysis, dwarf sph…
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,…
Indirect constraints to branon dark matter
J. A. R. Cembranos, A. de la Cruz-Dombriz, V. Gammaldi +1
If the present dark matter in the Universe annihilates into Standard Model particles, it must contribute to the gamma ray fluxes detected on the Earth. Here we briefly review the p…
Detection of branon dark matter with gamma ray telescopes
J. A. R. Cembranos, A. de la Cruz-Dombriz, V. Gammaldi +1
Branons are new degrees of freedom that appear in flexible brane-world models corresponding to brane fluctuations. These new fields can behave as standard weakly interacting massiv…
