Search for point sources of ultra-high-energy photons with the Telescope Array surface detector

Mitsuru Abe, Tareq Abu-Zayyad, M. Allen, Ryuji Azuma et autres

ABSTRACT The surface detector (SD) of the Telescope Array (TA) experiment allows us to detect indirectly photons with energies of the order of 1018 eV and higher, and to separate photons from the cosmic ray background. In this paper, we present the …

Mass composition of ultrahigh-energy cosmic rays with the Telescope Array Surface Detector data

Mitsuru Abe, Tareq Abu-Zayyad, M. Allen, Ryuji Azuma et autres

The results on ultrahigh-energy cosmic rays (UHECR) mass composition obtained with the Telescope Array surface detector are presented. The analysis employs the Boosted Decision tree (BDT) multivariate analysis built upon 14 observables related to both the properties of the shower front and …

The Cosmic Ray Energy Spectrum between 2 PeV and 2 EeV Observed with the TALE Detector in Monocular Mode

Mitsuru Abe, Tareq Abu-Zayyad, M. Allen, Ryuji Azuma et autres

Abstract We report on a measurement of the cosmic ray energy spectrum by the Telescope Array Low-Energy Extension (TALE) air fluorescence detector (FD). The TALE air FD is also sensitive to the Cherenkov light produced by shower particles. Low-energy cosmic rays, in …

Search for correlations between arrival directions of ultrahigh-energy cosmic rays detected by the Telescope Array experiment and a flux pattern from nearby starburst galaxies

Rasha U. Abbasi, Mitsuru Abe, Tareq Abu-Zayyad, Monica Allen et autres

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 starburst galaxies (SBGs). In this Letter, we tested the same hypothesis using cosmic rays …

Study of muons from ultrahigh energy cosmic ray air showers measured with the Telescope Array experiment

Mitsuru Abe, Tareq Abu-Zayyad, M. Allen, Ryuji Azuma et autres

One of the uncertainties in the interpretation of ultrahigh energy cosmic ray data comes from the hadronic interaction models used for air shower Monte Carlo (MC) simulations. The number of muons observed at the ground from ultrahigh energy cosmic ray--induced air showers …

Search for Anisotropy in the Ultra High Energy Cosmic Ray Spectrum using\n the Telescope Array Surface Detector

Mitsuru Abe, T. Abu‐Zayyad, M. Allen, R. Azuma et autres

The Telescope Array (TA) experiment is located in the western desert of Utah,\nUSA, and observes ultra high energy cosmic rays (UHECRs) in the Northern\nhemisphere. At the highest energies, $E>10$~EeV, the shape of cosmic ray energy\nspectrum may carry an imprint of the source …
