An upper limit on the electron-neutrino flux from the HiRes detector
R. U. Abbasi, T. Abu-Zayyad, M. Allen +64
Air-fluorescence detectors such as the High Resolution Fly's Eye (HiRes) detector are very sensitive to upward-going, Earth-skimming ultrahigh energy electron-neutrino-induced show…
First Observation of the Greisen-Zatsepin-Kuzmin Suppression
HiRes Collaboration
The High Resolution Fly's Eye (HiRes) experiment has observed the Greisen-Zatsepin-Kuzmin suppression (called the GZK cutoff) with a statistical significance of five standard devia…
Alternative Methods to Finding Patterns in HiRes Stereo Data
R. Abbasi
In this paper Ultra High Energy Cosmic Rays UHECRs data observed by the HiRes fluorescence detector in stereo mode is analyzed to search for events in the sky with an arrival direc…
A Likelihood Method for Measuring the Ultrahigh Energy Cosmic Ray Composition
HiRes Collaboration
Air fluorescence detectors traditionally determine the dominant chemical composit ion of the ultrahigh energy cosmic ray flux by comparing the averaged slant depth of the shower ma…
A Measurement of Time-Averaged Aerosol Optical Depth using Air-Showers Observed in Stereo by HiRes
s Eye Collaboration
Air fluorescence measurements of cosmic ray energy must be corrected for attenuation of the atmosphere. In this paper we show that the air-showers themselves can yield a measuremen…
Search for Point-Like Sources of Cosmic Rays with Energies above 10^18.5 eV in the HiRes-I Monocular Data-Set
s Eye Collaboration
We report the results of a search for point-like deviations from isotropy in the arrival directions of ultra-high energy cosmic rays in the northern hemisphere. In the monocular da…
