Testing effects of Lorentz invariance violation in the propagation of astroparticles with the Pierre Auger Observatory
The Pierre Auger Collaboration, P. Abreu, M. Aglietta +374
Lorentz invariance violation (LIV) is often described by dispersion relations of the form with delta different based on particle type , with…
Calibration of the Surface Array of the Pierre Auger Observatory
X. Bertou, P. S. Allison, C. Bonifazi +23
The Pierre Auger Observatory is designed to study cosmic rays of the highest energies ( eV). The ground array of the Observatory will consist of 1600 water Cherenkov dete…
On the energy of the protons producing the very high-energy astrophysical neutrinos
Esteban Roulet, Francesco Vissani
We study the distribution of the energy of the protons that can produce an astrophysical neutrino with a given observed energy, in the TeV--PeV range, both through or int…
Features of the energy spectrum of cosmic rays above eV using the Pierre Auger Observatory
The Pierre Auger Collaboration, A. Aab, P. Abreu +380
We report a measurement of the energy spectrum of cosmic rays above eV based on events. New results are presented: at about eV…
Measurement of the cosmic-ray energy spectrum above eV using the Pierre Auger Observatory
The Pierre Auger Collaboration, A. Aab, P. Abreu +380
We report a measurement of the energy spectrum of cosmic rays for energies above eV based on 215,030 events recorded with zenith angles below . A k…
Extragalactic cosmic rays diffusing from two populations of sources
Silvia Mollerach, Esteban Roulet
We consider the possibility of explaining the observed spectrum and composition of the cosmic rays with energies above eV in terms of two different extragalactic populati…
