Science highlights from the Fermi Large Area Telescope
  During its first three years of operation, the Fermi Gamma-ray Space Telescope has provided an unprecedented view of the high energy gamma-ray sky, and also performed direct measurements of the cosmic-ray leptons and searches for signals from dark matter. In this paper we present a short overview of some highlight results, shedding new light on the high-energy side of the Universe.
