A tentative gamma-ray line from Dark Matter annihilation at the Fermi Large Area Telescope
A tentative gamma-ray line from Dark Matter annihilation at the Fermi Large Area Telescope
The observation of a gamma-ray line in the cosmic-ray fluxes would be a smoking-gun signature for dark matter annihilation or decay in the Universe. We present an improved search for such signatures in the data of the Fermi Large Area Telescope (LAT), concentrating on energies between 20 and 300 GeV. …
