The Lateral Trigger Probability function for the Ultra-High Energy Cosmic Ray Showers detected by the Pierre Auger Observatory
The Pierre Auger Collaboration, P. Abreu, M. Aglietta +495
In this paper we introduce the concept of Lateral Trigger Probability (LTP) function, i.e., the probability for an extensive air shower (EAS) to trigger an individual detector of a…
The Pierre Auger Observatory V: Enhancements
The Pierre Auger Collaboration, P. Abreu, M. Aglietta +493
Ongoing and planned enhancements of the Pierre Auger Observatory
The exposure of the hybrid detector of the Pierre Auger Observatory
The Pierre Auger Collaboration
The Pierre Auger Observatory is a detector for ultra-high energy cosmic rays. It consists of a surface array to measure secondary particles at ground level and a fluorescence detec…
Measurement of the energy spectrum of cosmic rays above 10^18 eV using the Pierre Auger Observatory
The Pierre Auger Collaboration
We report a measurement of the flux of cosmic rays with unprecedented precision and statistics using the Pierre Auger Observatory. Based on fluorescence observations in coincidence…
Measurement of the Depth of Maximum of Extensive Air Showers above 10^18 eV
The Pierre Auger Collaboration
We describe the measurement of the depth of maximum, Xmax, of the longitudinal development of air showers induced by cosmic rays. Almost four thousand events above 10^18 eV observe…
Atmospheric effects on extensive air showers observed with the Surface Detector of the Pierre Auger Observatory
The Pierre Auger Collaboration
Atmospheric parameters, such as pressure (P), temperature (T) and density, affect the development of extensive air showers initiated by energetic cosmic rays. We have studied the i…
Limit on the diffuse flux of ultra-high energy tau neutrinos with the surface detector of the Pierre Auger Observatory
The Pierre Auger Collaboration
Data collected at the Pierre Auger Observatory are used to establish an upper limit on the diffuse flux of tau neutrinos in the cosmic radiation. Earth-skimming may interact…

The Pierre Auger Collaboration
The energy spectrum of cosmic rays above 2.5x10^18eV, derived from 20,000 events recorded at the Pierre Auger Observatory, is described. The spectral index gamma of the flux, J ~ E…
Upper limit on the cosmic-ray photon flux above 10^19 eV using the surface detector of the Pierre Auger Observatory
The Pierre Auger Collaboration
A method is developed to search for air showers initiated by photons using data recorded by the surface detector of the Auger Observatory. The approach is based on observables sens…
Upper limit on the diffuse flux of UHE tau neutrinos from the Pierre Auger Observatory
The Pierre Auger Collaboration
The surface detector array of the Pierre Auger Observatory is sensitive to Earth-skimming tau-neutrinos that interact in the Earth's crust. Tau leptons from charged-cur…
Correlation of the highest energy cosmic rays with nearby extragalactic objects
The Pierre Auger Collaboration
Using data collected at the Pierre Auger Observatory during the past 3.7 years, we demonstrated a correlation between the arrival directions of cosmic rays with energy above ~ 6x10…
Anisotropy studies around the galactic centre at EeV energies with the Auger Observatory
The Pierre Auger Collaboration
Data from the Pierre Auger Observatory are analyzed to search for anisotropies near the direction of the Galactic Centre at EeV energies. The exposure of the surface array in this…
An upper limit to the photon fraction in cosmic rays above 10^19 eV from the Pierre Auger Observatory
Pierre Auger Collaboration
An upper limit of 16% (at 95% c.l.) is derived for the photon fraction in cosmic rays with energies greater than 10^19 eV, based on observations of the depth of shower maximum perf…
