Recently I read a notice and after the relative paper titled “A Tentative Gamma-Ray Line from Dark Matter Annihilation at the Fermi Large Area Telescope”. The Fermi Large Area Telescope (also known with the name GLAST, Gamma-Ray Large Area Telescope) is an international mission designed with the aim to explore the sky at very high energies. It is a space telescope capable of detecting photons in the range from 30 MeV to 300 GeV. The Fermi space observatory is a NASA mission with a broad international collaboration (Italy, Japan, France, Sweden). After the activation in orbit, the mission has been dedicated to Enrico Fermi and nowadays it is known as the Fermi Gamma-Ray Telescope. The autor of the paper, independently from the Fermi official collaboration, claimed to observe a gamma-ray signature in the cosmic-ray coming from dark matter annihilation in the Universe (indeed the pair-annihilation of Galactic dark matter produce a monochromatic or internal bremsstrahlung gamma rays that rise from the continuous background).
