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…
Reionization, UV Luminosity and 21cm Sensitivity to Primordial Magnetic Fields: Impact of Energy Losses
Gaétan Facchinetti, Alexander Korochkin, Laura Lopez-Honorez +1
Magnetic fields with field strengths between G and a few Nanogauss are expected to exist today in the intergalactic medium (IGM). Their origin is unknown, but may be of…
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)…
UHECR deflections in the coherent Galactic magnetic field
Alexander Korochkin, Dmitri Semikoz, Peter Tinyakov
We study the deflections of ultra-high-energy cosmic rays in several widely used models of the coherent Galactic magnetic field (GMF), including PT11 (Pshirkov et al. [1]), JF12 (J…
Displacement of ultra-high-energy cosmic ray source images by the intergalactic magnetic field: the cases of Cen A and M83
K. Dolgikh, A. Korochkin, G. Rubtsov +2
The standard assumption about the influence of the turbulent intergalactic magnetic field (IGMF) on the images of ultra-high-energy cosmic rays (UHECR) sources is that the latter a…
