Search for signatures of magnetically-induced alignment in the arrival directions measured by the Pierre Auger Observatory
The Pierre Auger Collaboration, P. Abreu, M. Aglietta +496
We present the results of an analysis of data recorded at the Pierre Auger Observatory in which we search for groups of directionally-aligned events (or `multiplets') which exhibit…

The Pierre Auger Collaboration, P. Abreu, M. Aglietta +493
Studies of the cosmic ray energy spectrum at the highest energies with the Pierre Auger Observatory
The Pierre Auger Observatory III: Other Astrophysical Observations
The Pierre Auger Collaboration, P. Abreu, M. Aglietta +493
Astrophysical observations of ultra-high-energy cosmic rays with the Pierre Auger Observatory
The Pierre Auger Observatory II: Studies of Cosmic Ray Composition and Hadronic Interaction models
The Pierre Auger Collaboration, P. Abreu, M. Aglietta +493
Studies of the composition of the highest energy cosmic rays with the Pierre Auger Observatory, including examination of hadronic physics effects on the structure of extensive air…
Interdisciplinary Aspects of High-Energy Astrophysics
Guenter Sigl
Modern astrophysics, especially at GeV energy scales and above is a typical example where several disciplines meet: The location and distribution of the sources is the domain of as…
Lorentz Invariance Violation and Chemical Composition of Ultra High Energy Cosmic Rays
Andrey Saveliev, Luca Maccione, Guenter Sigl
Motivated by experimental indications of a significant presence of heavy nuclei in the cosmic ray flux at ultra high energies ($\gtrsim 10^{19} \eV$), we consider the effects of Pl…
