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 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…
Evidence for a mixed mass composition at the `ankle' in the cosmic-ray spectrum
The Pierre Auger Collaboration, A. Aab, P. Abreu +423
We report a first measurement for ultra-high energy cosmic rays of the correlation between the depth of shower maximum and the signal in the water Cherenkov stations of air-showers…
Large scale distribution of ultra high energy cosmic rays detected at the Pierre Auger Observatory with zenith angles up to 80
The Pierre Auger Collaboration
We present the results of an analysis of the large angular scale distribution of the arrival directions of cosmic rays with energy above 4 EeV detected at the Pierre Auger Observat…
