Analysis of large-scale anisotropy of ultra-high energy cosmic rays in HiRes data
R. U. Abbasi, T. Abu-Zayyad, M. Allen +59
Stereo data collected by the HiRes experiment over a six year period are examined for large-scale anisotropy related to the inhomogeneous distribution of matter in the nearby Unive…
Indications of Proton-Dominated Cosmic Ray Composition above 1.6 EeV
R. U. Abbasi, T. Abu-Zayyad, M. Al-Seady +57
We report studies of ultra-high energy cosmic ray composition via analysis of depth of airshower maximum (Xmax), for airshower events collected by the High Resolution Fly's Eye (Hi…
Measurement of the Flux of Ultra High Energy Cosmic Rays by the Stereo Technique
R. U. Abbasi, T. Abu-Zayyad, M. Al-Seady +60
The High Resolution Fly's Eye experiment has measured the flux of ultrahigh energy cosmic rays using the stereoscopic air fluorescence technique. The HiRes experiment consists of t…
Search for Correlations between HiRes Stereo Events and Active Galactic Nuclei
R. U. Abbasi, T. Abu-Zayyad, M. Allen +61
We have searched for correlations between the pointing directions of ultrahigh energy cosmic rays observed by the High Resolution Fly's Eye experiment and Active Galactic Nuclei (A…
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…
Measurement of Aerosols at the Pierre Auger Observatory
S. Y. BenZvi, F. Arqueros, R. Cester +38
The air fluorescence detectors (FDs) of the Pierre Auger Observatory are vital for the determination of the air shower energy scale. To compensate for variations in atmospheric con…
