  1. 126. Positron fraction, electron and positron spectra measured by AMS02
    Cecilia Pizzolotto (INFN and ASDC)
    02/10/2014, 14:00
    A precise measurement by AMS02 of the electron spectrum up to 700 GeV and of the positron spectrum and positron fraction in primary cosmic rays up 500 GeV will be presented. In this contribution, we will review the analysis performed to determine the individual fluxes that for the first time have been extended to such high energies. The combined measurement of the cosmic-ray electron and...

  2. 127. AMS-02: cosmic electron and positron (e+ + e-) spectrum up to 1 TeV

    The AMS-02 spectrometer, on the ISS since 2011, performs highly accurate measurements of cosmic rays up to the TeV region. We review the analysis of the cosmic (e+ + e-) flux in the energy range between 0.5 GeV and 1 TeV, based on 41 billion events. The high statistics and detector energy resolution allow for a study of the spectral shape of unprecedented quality, thus improving our...

  3. 166. Probing cosmic rays in nearby giant molecular clouds with the Fermi Large Area Telescope

    We report the results of our study of the energy spectra and absolute fluxes of cosmic rays (CRs) in the Local Galaxy based on a five-year γ-ray observation with the Fermi Large Area Telescope (LAT) of eight nearby giant molecular clouds (GMCs) belonging to the Gould Belt. The γ-ray signals obtained with high statistical significance allow the determination of γ-ray spectra above 300 MeV with...

  4. 189. Gamma-ray, neutrino and antiproton fluxes from TeV Dark Matter at the Galactic Center.

    oral
    I will show that the collection of data of the years 2004, 2005 and 2006 of the gamma-ray flux observed by HESS from the J1745-290 Galactic Center source is well fitted as the secondary gamma-ray photons generated from Dark Matter annihilating into Standard Model particles in combination with a simple power law background. The model independent fits are performed for all the possible channels...

  5. 187. AGILE highlights in gamma-ray astrophysics
    Dr Giovanni Piano (INAF-IAPS Roma)
    02/10/2014, 15:20
    oral
    The AGILE space mission, currently in its eight year of operations in orbit, obtained a large number of crucial and unexpected findings. We review the main results for both Galactic and extragalactic sources, and outline some of the most surprising discoveries: gamma-ray flares from the Crab Nebula, detection of HE emission from Cygnus X-1 and Cygnus X-3 in coincidence with special spectral...
