Search for correlations of the arrival directions of ultra-high energy cosmic ray with extragalactic objects as observed by the telescope array experiment
T. Abu-Zayyad, R. Aida, M. Allen +141
We search for correlations between positions of extragalactic objects and arrival directions of Ultra-High Energy Cosmic Rays (UHECRs) with primary energy EeV as observe…
Energy Spectrum of Ultra-High Energy Cosmic Rays Observed with the Telescope Array Using a Hybrid Technique
T. Abu-Zayyad, R. Aida, M. Allen +141
We measure the spectrum of cosmic rays with energies greater than eV with the Fluorescence Detectors (FDs) and the Surface Detectors (SDs) of the Telescope Array Experi…
The Energy Spectrum of Ultra-High-Energy Cosmic Rays Measured by the Telescope Array FADC Fluorescence Detectors in Monocular Mode
The Telescope Array Collaboration, T. Abu-Zayyad, R. Aida +141
We present a measurement of the energy spectrum of ultra-high-energy cosmic rays performed by the Telescope Array experiment using monocular observations from its two new FADC-base…
Upper limit on the flux of photons with energies above 10^19 eV using the Telescope Array surface detector
T. Abu-Zayyad, R. Aida, M. Allen +138
We search for ultra-high energy photons by analyzing geometrical properties of shower fronts of events registered by the Telescope Array surface detector. By making use of an event…
Search for Anisotropy of Ultra-High Energy Cosmic Rays with the Telescope Array Experiment
T. Abu-Zayyad, R. Aida, M. Allen +139
We study the anisotropy of Ultra-High Energy Cosmic Ray (UHECR) events collected by the Telescope Array (TA) detector in the first 40 months of operation. Following earlier studies…
The Energy Spectrum of Telescope Array's Middle Drum Detector and the Direct Comparison to the High Resolution Fly's Eye Experiment
T. Abu-Zayyad, R. Aida, M. Allen +137
The Telescope Array's Middle Drum fluorescence detector was instrumented with telescopes refurbished from the High Resolution Fly's Eye's HiRes-1 site. The data observed by Middle…
