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,…
Observations of the Origin of Downward Terrestrial Gamma-Ray Flashes
J. W. Belz, P. R. Krehbiel, J. Remington +137
In this paper we report the first close, high-resolution observations of downward-directed terrestrial gamma-ray flashes (TGFs) detected by the large-area Telescope Array cosmic ra…
Measurement of the Proton-Air Cross Section with Telescope Array's Black Rock Mesa and Long Ridge Fluorescence Detectors, and Surface Array in Hybrid Mode
R. U. Abbasi, M. Abe, T. Abu-Zayyad +140
Ultra high energy cosmic rays provide the highest known energy source in the universe to measure proton cross sections. Though conditions for collecting such data are less controll…
Search for Ultra-High-Energy Neutrinos with the Telescope Array Surface Detector
R. U. Abbasi, M. Abe, T. Abu-Zayyad +133
We present an upper limit on the flux of ultra-high-energy down-going neutrinos for $E > 10^{18}\ \mbox{eV}$ derived with the nine years of data collected by the Telescope Array su…
Constraints on the diffuse photon flux with energies above eV using the surface detector of the Telescope Array experiment
Telescope Array Collaboration, R. U. Abbasi, M. Abe +139
We present the results of the search for ultra-high-energy photons with nine years of data from the Telescope Array surface detector. A multivariate classifier is built upon 16 rec…
Mass composition of ultra-high-energy cosmic rays with the Telescope Array Surface Detector Data
Telescope Array Collaboration, R. U. Abbasi, M. Abe +139
The results on ultra-high-energy cosmic rays (UHECR) mass composition obtained with the Telescope Array surface detector are presented. The analysis employs the boosted decision tr…
Study of muons from ultra-high energy cosmic ray air showers measured with the Telescope Array experiment
Telescope Array Collaboration, R. U. Abbasi, M. Abe +138
One of the uncertainties in interpretation of ultra-high energy cosmic ray (UHECR) data comes from the hadronic interaction models used for air shower Monte Carlo (MC) simulations.…
Depth of Ultra High Energy Cosmic Ray Induced Air Shower Maxima Measured by the Telescope Array Black Rock and Long Ridge FADC Fluorescence Detectors and Surface Array in Hybrid Mode
Telescope Array Collaboration, R. U. Abbasi, M. Abe +135
The Telescope Array observatory utilizes fluorescence detectors and surface detectors to observe air showers produced by ultra high energy cosmic rays in the Earth's atmosphere. Co…
