Dr Martin Tluczykont (University of Hamburg)6/22/16, 2:30 PMThe very high energy gamma-ray regime is the key to several questions in high energy astrophysics, the most prominent being the search for the origin of cosmic rays. Observations of gamma rays up to several 100 TeV are particularly important to spectrally resolve the cutoff regime of the long-sought Pevatrons, the accelerators of PeV cosmic rays. The HiSCORE timing array is part of the...Go to contribution page

Prof. Leonid Kuzmichev (SINP MSU)6/22/16, 3:00 PMThe gamma-ray observatory TAIGA (Tunka Advanced Instrument for cosmic ray physics and Gamma Astronomy) is designed for the study of gamma rays and fluxes of charged cosmic rays in the energy range 1013 eV – 1018 eV. The installation will include a network of wide-angle (FOV - 0.6 sr) Cherenkov stations and up to 16 IACTs ( FOV -10×10 degrees) on an area of 5 km² and muon detectors with a...Go to contribution page

Armando Di Matteo (AQ)6/22/16, 3:30 PMWe present a combined fit of a simple astrophysical model of UHECR sources to both the energy spectrum and mass composition data measured by the Pierre Auger Observatory. The fit has been performed for energies above 5 EeV, i.e. the region of the all-particle spectrum above the so-called "ankle" feature. The astrophysical model we adopted consists of identical sources uniformly distributed in...Go to contribution page

Giovanni Marsella (LE)6/22/16, 4:00 PMIt is planned to operate the Pierre Auger Observatory until the end of 2024. An Upgrade of the experiment has been proposed in order to provide additional measurements to allow to elucidate the mass composition and the origin of the flux suppression at the highest energies, to search for a flux contribution of protons up to the highest energies and to reach a sensitivity to a contribution as...Go to contribution page
