Description

Cosmic rays are a probe of the most energetic processes in the Universe and may encode signatures of dark-matter particles annihilation or decay. The Large Area Telescope on board the Fermi Gamma-ray Space Telescope indirectly traces cosmic rays throughout the Galaxy thanks to the diffuse gamma-ray emission produced by inelastic collisions of cosmic-ray nuclei with interstellar gas and by electrons and positrons that undergo bremsstrahlung or inverse-Compton scattering. I will review the main results from Fermi in the field with focus on the uncertainties of the backgrounds for dark-matter searches.
