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…
Combined fit of spectrum and composition data as measured by the Pierre Auger Observatory
The Pierre Auger Collaboration, A. Aab, P. Abreu +397
We 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 h…
A targeted search for point sources of EeV photons with the Pierre Auger Observatory
The Pierre Auger Collaboration, A. Aab, P. Abreu +397
Simultaneous measurements of air showers with the fluorescence and surface detectors of the Pierre Auger Observatory allow a sensitive search for EeV photon point sources. Several…
Multi-resolution anisotropy studies of ultrahigh-energy cosmic rays detected at the Pierre Auger Observatory
The Pierre Auger Collaboration, A. Aab, P. Abreu +400
We report a multi-resolution search for anisotropies in the arrival directions of cosmic rays detected at the Pierre Auger Observatory with local zenith angles up to and…
Search for ultrarelativistic magnetic monopoles with the Pierre Auger Observatory
The Pierre Auger Collaboration, A. Aab, P. Abreu +411
We present a search for ultra-relativistic magnetic monopoles with the Pierre Auger Observatory. Such particles, possibly a relic of phase transitions in the early universe, would…
