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)…
Weak emission line quasar SDSS J101353.45+492758.1 I. Continuum fitting
Laetitia Gibaud, Marek NikoÅajuk, Piotr Å»ycki +3
We present a broadband study of the WLQ SDSS J101353.45+492758.1, which displays a nearly featureless UV-optical spectrum with only a weak Mg II line alongside an exceptionally low…
