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…
Ultra High Energy Cosmic Rays and the Auger Observatory
Antoine Letessier-Selvon
In this proceeding we present the construction status and the performances of the Pierre Auger Observatory together with the first results obtained with our initial 18 month of dat…
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…
Detection of inclined and horizontal showers in the Pierre Auger Observatory
V. Van Elewyck
The Pierre Auger Observatory can detect with high efficiency the air showers induced by ultra-high energy cosmic rays incident at large (> 60 deg.) zenith angles. We describe here…
Search for localized excess fluxes in Auger sky maps and prescription results
The Pierre Auger Collaboration
Using the first surface detector data of the Pierre Auger Observatory, we present the results of a blind search for overdensities in the cosmic ray flux with respect to isotropic e…
Measurement of the Lateral Distribution Function of UHECR Air Showers with the Pierre Auger Observatory
D. Barnhill, P. Bauleo, M. T. Dova +11
The Pierre Auger Observatory is being used to study cosmic rays with energies larger than 10 EeV. An essential quantity that must be deduced from data is the lateral distribution f…
