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…

First detection of VHE gamma-ray signal from the FSRQ TON 0599

MAGIC Collaboration, K. Abe, S. Abe +245

TON\,0599 (z=0.7247) belongs to the few flat spectrum radio quasars (FSRQs) detected in the very high energy (VHE, \,GeV) gamma-ray band. Its redshift makes it currently o…
