First High-speed Video Camera Observations of a Lightning Flash Associated with a Downward Terrestrial Gamma-ray Flash
R. U. Abbasi, M. M. F. Saba, J. W. Belz +146
In this paper, we present the first high-speed video observation of a cloud-to-ground lightning flash and its associated downward-directed Terrestrial Gamma-ray Flash (TGF). The op…
Observation of Variations in Cosmic Ray Single Count Rates During Thunderstorms and Implications for Large-Scale Electric Field Changes
R. U. Abbasi, T. Abu-Zayyad, M. Allen +160
We present the first observation by the Telescope Array Surface Detector (TASD) of the effect of thunderstorms on the development of cosmic ray single count rate intensity over a 7…
Indications of a Cosmic Ray Source in the Perseus-Pisces Supercluster
Telescope Array Collaboration, R. U. Abbasi, T. Abu-Zayyad +155
The Telescope Array Collaboration has observed an excess of events with in the data which is centered at (RA, dec) = (, ). This is n…
Search for Large-scale Anisotropy on Arrival Directions of Ultra-high-energy Cosmic Rays Observed with the Telescope Array Experiment
Telescope Array Collaboration, R. U. Abbasi, M. Abe +141
Motivated by the detection of a significant dipole structure in the arrival directions of ultrahigh-energy cosmic rays above 8 EeV reported by the Pierre Auger Observatory (Auger),…
Evidence for a Supergalactic Structure of Magnetic Deflection Multiplets of Ultra-High Energy Cosmic Rays
Telescope Array Collaboration, R. U. Abbasi, M. Abe +140
Evidence for a large-scale supergalactic cosmic ray multiplet (arrival directions correlated with energy) structure is reported for ultra-high energy cosmic ray (UHECR) energies ab…
Testing a reported correlation between arrival directions of ultrahigh-energy cosmic rays and a flux pattern from nearby starburst galaxies using Telescope Array data
Telescope Array Collaboration, R. U. Abbasi, M. Abe +138
The Pierre Auger Collaboration (Auger) recently reported a correlation between the arrival directions of cosmic rays with energies above 39 EeV and the flux pattern of 23 nearby st…
The Cosmic-Ray Energy Spectrum between 2 PeV and 2 EeV Observed with the TALE detector in monocular mode
R. U. Abbasi, M. Abe, T. Abu-Zayyad +137
We report on a measurement of the cosmic ray energy spectrum by the Telescope Array Low-Energy Extension (TALE) air fluorescence detector. The TALE air fluorescence detector is als…
Evidence of Intermediate-Scale Energy Spectrum Anisotropy of Cosmic Rays E10 eV with the Telescope Array Surface Detector
R. U. Abbasi, M. Abe, T. Abu-Zayyad +136
An intermediate-scale energy spectrum anisotropy has been found in the arrival directions of ultra-high energy cosmic rays of energies above eV in the northern hemisphe…
