The performance of the TA4 surface detector array: 4.3 years of the first-half expansion

Telescope Array Collaboration, R. U. Abbasi, T. Abu-Zayyad +126

The Telescope Array (TA) experiment aims to reveal the origin of ultra-high-energy cosmic rays (UHECRs) by observing air showers using surface detectors (SDs), which spread over an…

Searching for EeV photons with Telescope Array Surface Detector and neural networks

Telescope Array Collaboration, R. U. Abbasi, T. Abu-Zayyad +126

Ultra-high-energy photons play an important role in probing astrophysical models and beyond-Standard-Model scenarios. We report updated limits on the diffuse photon flux using Tele…

Isotropy of cosmic rays beyond eV favors their heavy mass composition

Telescope Array Collaboration, R. U. Abbasi, Y. Abe +138

We report an estimation of the injected mass composition of ultra-high energy cosmic rays (UHECRs) at energies higher than 10 EeV. The composition is inferred from an energy-depend…

Mass composition of ultra-high energy cosmic rays from distribution of their arrival directions with the Telescope Array

Telescope Array Collaboration, R. U. Abbasi, Y. Abe +138

We use a new method to estimate the injected mass composition of ultrahigh cosmic rays (UHECRs) at energies higher than 10 EeV. The method is based on comparison of the energy-depe…

An extremely energetic cosmic ray observed by a surface detector array

Telescope Array Collaboration

Cosmic rays are energetic charged particles from extraterrestrial sources, with the highest energy events thought to come from extragalactic sources. Their arrival is infrequent, s…

Rejecting noise in Baikal-GVD data with neural networks

I. Kharuk, G. Rubtsov, G. Safronov

Baikal-GVD is a large (1 km) underwater neutrino telescope installed in the fresh waters of Lake Baikal. The deep lake water environment is pervaded by background light,…

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…

Deep learning method for identifying mass composition of ultra-high-energy cosmic rays

O. Kalashev, I. Kharuk, M. Kuznetsov +4

We introduce a novel method for identifying the mass composition of ultra-high-energy cosmic rays using deep learning. The key idea of the method is to use a chain of two neural ne…

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…
