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…

Neutrino probe of cosmic ray astrophysics and new physics at sub-fermi distances

Luis A. Anchordoqui

We show that if the evolution of cosmic ray sources follows that of active galactic nuclei, the upper limit on the diffuse flux of tau neutrinos from the Pierre Auger Observatory m…

Investigation of Hadronic Interactions at Ultra-High Energies with the Pierre Auger Observatory

Ralf Ulrich

The aim of the Pierre Auger Observatory is the investigation of the nature of cosmic ray particles at ultra-high energies. It can simultaneously observe the longitudinal air shower…

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…

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…

Measurements of the Muon Content of UHECR Air Showers with the Pierre Auger Observatory

Fabian Schmidt

The Pierre Auger Observatory, recently completed, has been operational since 2004. As a hybrid experiment, it allows for a wide range of measurements of UHECR-induced extensive air…
