Sites for Gamma-ray Astronomy in Argentina
A. C. Rovero, G. E. Romero, I. Allekotte +9
We have searched for possible sites in Argentina for the installation of large air Cherenkov telescope arrays and water Cherenkov systems. At present seven candidates are identifie…
Underground Muon Counters as a Tool for Composition Analyses
A. D. Supanitsky, A. Etchegoyen, G. Medina-Tanco +3
The transition energy from galactic to extragalactic cosmic ray sources is still uncertain, but it should be associated either with the region of the spectrum known as the second k…
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…
Enhancing the Pierre Auger Observatory to the 10^{17} to 10^{18.5} eV Range: Capabilities of an Infill Surface Array
M. C. Medina, M. Gomez Berisso, I. Allekotte +3
The Pierre Auger Observatory has been designed to study the highest-energy cosmic rays in nature (E > 10^{18.5} eV). The determination of their arrival direction, energy and compos…
Aperture calculation of the Pierre Auger Observatory surface detector
D. Allard, I. Allekotte, E. Armengaud +11
We determine the instantaneous aperture and integrated exposure of the surface detector of the Pierre Auger Observatory, taking into account the trigger efficiency as a function of…
The importance of muon information on primary mass discrimination of ultra-high energy cosmic rays
D. Supanitsky, A. Tiba, G. Medina-Tanco +7
Several methods can be used to perform statistical inference of primary composition of cosmic rays measured with water Cerenkov detectors as those in use at the Pierre Auger Southe…
The trigger system of the Pierre Auger Surface Detector: operation, efficiency and stability
D. Allard, E. Armengaud, I. Allekotte +31
The trigger system of the Surface Detector (SD) of the Pierre Auger Observatory is described, from the identification of candidate showers ( EeV) at the level of a single stat…
A Study Of Very Inclined Showers In The Pierre Auger Observatory
M. Ave
The Engineering Array of the Auger Observatory has been running successfully since 2001 and inclined showers have been recorded from the start. We have analysed the events with zen…
Calibration of the Pierre Auger fluorescence detector
M. D. Roberts
The absolute calibration of an air fluorescence detector (FD) is an important element in correctly determining the energy of detected cosmic rays. The absolute calibration relates…
