Outdoor Systems Performace and Upgrade
L. Lopes, S. Andringa, P. Assis +17
Over the last two decades, the possibility of using RPCs in outdoors systems has increased considerably. Our group has participated in this effort having installed several systems…
Constraining the sources of ultra-high-energy cosmic rays across and above the ankle with the spectrum and composition data measured at the Pierre Auger Observatory
The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +365
In this work we present the interpretation of the energy spectrum and mass composition data as measured by the Pierre Auger Collaboration above eV. We use an ast…
Arrival Directions of Cosmic Rays above 32 EeV from Phase One of the Pierre Auger Observatory
The Pierre Auger Collaboration, P. Abreu, M. Aglietta +372
A promising energy range to look for angular correlation between cosmic rays of extragalactic origin and their sources is at the highest energies, above few tens of EeV ($1\:{\rm E…
A search for photons with energies above eV using hybrid data from the low-energy extensions of the Pierre Auger Observatory
The Pierre Auger Collaboration, P. Abreu, M. Aglietta +373
Ultra-high-energy photons with energies exceeding eV offer a wealth of connections to different aspects of cosmic-ray astrophysics as well as to gamma-ray and neutrino as…
Limits to gauge coupling in the dark sector set by the non-observation of instanton-induced decay of Super-Heavy Dark Matter in the Pierre Auger Observatory data
The Pierre Auger Collaboration, P. Abreu, M. Aglietta +374
Instantons, which are non-perturbative solutions to Yang-Mills equations, provide a signal for the occurrence of quantum tunneling between distinct classes of vacua. They can give…
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…
