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 +128
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…
Cosmic ray mass composition measurement in the energy range from eV to eV observed with the TALE hybrid detector
Telescope Array Collaboration, R. U. Abbasi, T. Abu-Zayyad +126
We report on the cosmic ray mass composition measured by the Telescope Array Low-energy Extension (TALE) hybrid detector. The TALE detector consists of a fluorescence detector (FD)…
Interstellar Polarization Survey. V. Galactic magnetic field tomography in the spiral arms using optical and near-infrared starlight polarization
Y. Angarita, M. J. F. Versteeg, M. Haverkorn +5
Interstellar linear polarization occurs when starlight passes through elongated dust grains aligned by interstellar magnetic fields. The observed polarization can come from differe…
