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…
Studies of systematic uncertainties in the estimation of the monocular aperture of the HiRes experiment
HiRes Collaboration
We have studied several sources of systematic uncertainty in calculating the aperture of the High Resolution Fly's Eye experiment (HiRes) in monocular mode, primarily as they affec…
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…
Search for Cross-Correlations of Ultra--High-Energy Cosmic Rays with BL Lacertae Objects
s Eye Collaboration
Data taken in stereo mode by the High Resolution Fly's Eye (HiRes) air fluorescence experiment are analyzed to search for correlations between the arrival directions of ultra--high…
Measurement of Pressure Dependent Fluorescence Yield of Air: Calibration Factor for UHECR Detectors
The Fuorescence in Air from Showers, Collaboration
In a test experiment at the Final Focus Test Beam of the Stanford Linear Accelerator Center, the fluorescence yield of 28.5 GeV electrons in air and nitrogen was measured. The meas…
A Study of the Composition of Ultra High Energy Cosmic Rays Using the High Resolution Fly's Eye
s Eye Collaboration
The composition of Ultra High Energy Cosmic Rays (UHECR) is measured with the High Resolution Fly's Eye cosmic ray observatory (HiRes) data using the Xmax technique. Data were coll…
Study of Small-Scale Anisotropy of Ultrahigh Energy Cosmic Rays Observed in Stereo by HiRes
s Eye Collaboration
The High Resolution Fly's Eye (HiRes) experiment is an air fluorescence detector which, operating in stereo mode, has a typical angular resolution of 0.6 degrees and is sensitive t…
Monocular Measurement of the Spectrum of UHE Cosmic Rays by the FADC Detector of the HiRes Experiment
s Eye Collaboration
We have measured the spectrum of UHE cosmic rays using the Flash ADC (FADC) detector (called HiRes-II) of the High Resolution Fly's Eye experiment running in monocular mode. We des…
Measurement of the Flux of Ultrahigh Energy Cosmic Rays from Monocular Observations by the High Resolution Fly's Eye Experiment
s Eye Collaboration
We have measured the cosmic ray spectrum above 10^17.2 eV using the two air fluorescence detectors of the High Resolution Fly's Eye observatory operating in monocular mode. We desc…
A Measurement of the Average Longitudinal Development Profile of Cosmic Ray Air Showers Between 10^{17}eV and 10^{18}eV
T. Abu-Zayyad et. al
The average extensive air shower longitudinal development profile as a function of shower age in the energy range from 10 to 10eV is measured using data from the hybr…
