    The Fermi Large Area Telescope (LAT) has been exploring the gamma-ray sky for more than eight years, observing many powerful events happening in our Galaxy, in a range of energies from less than one hundred MeV up to few TeV. It provides essential information on the physical processes occurring at the source, involving both leptons and hadrons, in order to understand the mechanisms responsible...

    Axions and axion-like particles (ALPs) are a generic prediction of many extensions of the Standard Model. They are attracting growing interest as they are good candidates for cold dark matter, and -- in the case of ALPs -- they also give rise to very interesting effects in high -energy astrophysics for suitable values of the parameters. In the first place, photon-ALP oscillations considerably...

    Cosmological observations indicate that approximately 27% of the energy density of the universe is in the form of dark matter which is non-baryonic. The nature of dark matter is an open question in modern physics. A well motivated candidate constituent is a weakly interacting massive particle (WIMP) with mass in the range between O(10)GeV and O(100)TeV. The annihilation radiation from such...

  5. 107. Statistical Measurement of the Gamma-ray Source Count Distribution as a Function of Energy

    Statistical properties of photon count maps have recently been proven to provide a sensitive observable for characterizing gamma-ray source populations and for measuring the composition of the gamma-ray sky with high accuracy. In this contribution, we generalize the use of the standard 1-point probability distribution function (1pPDF) to decompose the high-latitude gamma-ray emission observed...
