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…
