Anisotropy and chemical composition of ultra-high energy cosmic rays using arrival directions measured by the Pierre Auger Observatory
The Pierre Auger Collaboration, P. Abreu, M. Aglietta +490
The Pierre Auger Collaboration has reported evidence for anisotropy in the distribution of arrival directions of the cosmic rays with energies eV. Thes…
The Fluorescence Detector of the Pierre Auger Observatory
The Pierre Auger Collaboration, J. Abraham, P. Abreu +515
The Pierre Auger Observatory is a hybrid detector for ultra-high energy cosmic rays. It combines a surface array to measure secondary particles at ground level together with a fluo…

The Pierre Auger Collaboration, J. Abraham, P. Abreu +470
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…
Upper limit on the cosmic-ray photon fraction at EeV energies from the Pierre Auger Observatory
The Pierre Auger Collaboration, J. Abraham, P. Abreu +458
From direct observations of the longitudinal development of ultra-high energy air showers performed with the Pierre Auger Observatory, upper limits of 3.8%, 2.4%, 3.5% and 11.7% (a…
The Surface Detector System of the Pierre Auger Observatory
I. Allekotte, A. F. Barbosa, P. Bauleo +17
The Pierre Auger Observatory is designed to study cosmic rays with energies greater than 10^{19} eV. Two sites are envisaged for the observatory, one in each hemisphere, for comple…
Correlation of the highest-energy cosmic rays with the positions of nearby active galactic nuclei
The Pierre Auger Collaboration
Data collected by the Pierre Auger Observatory provide evidence for anisotropy in the arrival directions of the cosmic rays with the highest energies, which are correlated with the…
Search for Ultra-High Energy Photons with the Pierre Auger Observatory
M. D. Healy
Data taken at the Pierre Auger Observatory are used to search for air showers initiated by ultra-high energy (UHE) photons. Results of searches are reported from hybrid observation…
Composition of UHECR and the Pierre Auger Observatory Spectrum
Katsushi Arisaka, Graciela B. Gelmini, Matthew Healy +2
We fit the recently published Pierre Auger ultra-high energy cosmic ray spectrum assuming that either nucleons or nuclei are emitted at the sources. We consider the simplified case…
Composition-sensitive parameters measured with the surface detector of the Pierre Auger Observatory
M. D. Healy
A key step towards the understanding of the origin of ultra-high energy cosmic rays is their mass composition. Primary photons and neutrinos produce markedly different showers from…
