    High-Energy Emission from Pulsars and their Systems, 12/2010
    Book Chapter

    The Large Area Telescope on-board the Fermi Gamma-Ray Space Telescope has collected more than 8 million cosmic ray electrons with energy above 7 GeV since the inception of its science operation on orbit. The observed spectrum has a harder spectral index than previously reported instances, which suggests the presence of nearby sources of high energy electrons. One viable candidate is nearby pulsars, possibly some of those recently discovered by Fermi. At the same time the dark matter origin of such sources cannot be ruled out. In this paper I present the Fermi LAT high statistics measurement of the cosmic-ray electron spectrum and its interpretation in terms of astrophysical sources for high energy electrons and a standard cosmic-ray propagation model.
