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…
Search for Point Sources of Ultra--High-Energy Cosmic Rays Above 10^19 eV Using a Maximum Likelihood Ratio Test
Stefan Westerhoff, Chad B. Finley
We present the results of a search for cosmic ray point sources at energies above 10^19 eV in the HiRes stereo data set. The analysis is based on a maximum likelihood ratio test us…
Search for Cross-Correlations of Ultra--High-Energy Cosmic Rays with BL Lacertae Objects
Chad B. Finley, Stefan Westerhoff
We present the results of searches for correlation between ultra--high-energy cosmic rays observed in stereo mode by the High Resolution Fly's Eye (HiRes) experiment and objects of…
