The gamma-ray sky under a 'new' light

During the last year the Gamma-Ray sky has glowed of new light: The PAMELA experiment, the Pierre Auger Observatory, the AGILE satellite, and the Fermi Gamma-ray Space Telescope are contributing in an unprecedented way to the unveiling of the cosmic distribution of gamma-ray sources and their viable relation with cosmic rays. The Alpha Magnetic Spectrometer, to be launched next July 2010, will add, for the first time, a precious energetic window, up to a few TeV, to this exciting investigation. We analyze the perspectives of AMS results and the possibilities for the detection of Galactic and Extragalactic gammaray astrophysical sources like Pulsars, Microquasars, Gamma-Ray Bursts, and Active Galactic Nuclei. © 2010 by World Scientific Publishing Co.
