Abstract

With its excellent sensitivity, large field of view, broad energy coverage, and good per-photon angular resolution, the Large Area Telescope aboard the Fermi Gamma-ray Space Telescope satellite provides us with an unprecedented view of the high-energy Universe, revealing a large diversity of cosmic particle accelerators that are active at various scales. We present in this paper a selection of science highlights of the Fermi mission, with particular emphasis on results that are relevant for cosmic-ray physics. We cover observations of supernova remnants and studies of interstellar gamma-ray emission, reaching from the vicinity of the solar system out to the more distant starburst galaxies.
