Composition of Primary Cosmic-Ray Nuclei at High Energies
M. Ave, P. J. Boyle, F. Gahbauer +5
The TRACER instrument (``Transition Radiation Array for Cosmic Energetic Radiation'') has been developed for direct measurements of the heavier primary cosmic-ray nuclei at high en…
A Model-Independent Method of Determining Energy Scale and Muon Number in Cosmic Ray Surface Detectors
Fabian Schmidt, Maximo Ave, Lorenzo Cazon +1
Surface detector arrays are designed to measure the spectrum and composition of high-energy cosmic rays by detecting the secondary particle flux of the Extensive Air Showers (EAS)…
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…
Temperature and Humidity Dependence of Air Fluorescence Yield measured by AIRFLY
M. Ave
The fluorescence detection of ultra high energy cosmic rays requires a detailed knowledge of the fluorescence light emission from nitrogen molecules over a wide range of atmospheri…
Energy Dependence of Air Fluorescence Yield measured by AIRFLY
M. Ave
In the fluorescence detection of ultra high energy (> 10**18 eV) cosmic rays, the number of emitted fluorescence photons is assumed to be proportional to the energy deposited in ai…
Applying Extensive Air Shower Universality to Ground Detector Data
Fabian Schmidt, Maximo Ave, Lorenzo Cazon +1

Maximo Ave, N. Busca, A. V. Olinto +2
We calculate the flux of neutrinos generated by the propagation of ultra-high energy iron over cosmological distances and show that even if ultra-high energy cosmic rays are compos…
A Study Of Very Inclined Showers In The Pierre Auger Observatory

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…
Probing TeV gravity with extensive air-showers
Maximo Ave, Eun-Joo Ahn, Marco Cavaglia +1
Particle collisions with center-of-mass energy larger than the fundamental gravitational scale can generate non perturbative gravitational objects such as black holes and branes. I…
