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…
Surface detectors of the TAx4 experiment
Telescope Array Collaboration, R. U. Abbasi, M. Abe +145
Telescope Array (TA) is the largest ultrahigh energy cosmic-ray (UHECR) observatory in the Northern Hemisphere. It explores the origin of UHECRs by measuring their energy spectrum,…
Development of the new multi-beam receiver and telescope control system for NASCO
Atsushi Nishimura, Akio Ohama, Kimihiro Kimura +59
We report the current status of the NASCO (NAnten2 Super CO survey as legacy) project which aims to provide all-sky CO data cube of southern hemisphere using the NANTEN2 4-m submil…
The Cosmic-Ray Composition between 2 PeV and 2 EeV Observed with the TALE Detector in Monocular Mode
Telescope Array Collaboration
We report on a measurement of the cosmic ray composition by the Telescope Array Low-Energy Extension (TALE) air fluorescence detector (FD). By making use of the Cherenkov light sig…
