Search for astrophysical PeV gamma rays from point sources with Carpet-2
D. D. Dzhappuev, I. M. Dzaparova, E. A. Gorbacheva +14
Early results of the search for E_γ>1 PeV cosmic photons from point sources with the data of Carpet-2, an air-shower array equipped with a 175 m^2 muon detector, are presented. The…
Constraints on the diffuse photon flux with energies above eV using the surface detector of the Telescope Array experiment
Telescope Array Collaboration, R. U. Abbasi, M. Abe +139
We present the results of the search for ultra-high-energy photons with nine years of data from the Telescope Array surface detector. A multivariate classifier is built upon 16 rec…
Testing a reported correlation between arrival directions of ultrahigh-energy cosmic rays and a flux pattern from nearby starburst galaxies using Telescope Array data
Telescope Array Collaboration, R. U. Abbasi, M. Abe +138
The Pierre Auger Collaboration (Auger) recently reported a correlation between the arrival directions of cosmic rays with energies above 39 EeV and the flux pattern of 23 nearby st…
Search for anomalous features in gamma-ray blazar spectra corrected for the absorption on the extragalactic background light
Alexander Korochkin, Grigory Rubtsov, Sergey Troitsky
We consider the ensemble of very-high-energy gamma-ray sources observed at distances and energies where a significant absorption of gamma rays is expected due to pair production on…
Mass composition of ultra-high-energy cosmic rays with the Telescope Array Surface Detector Data
Telescope Array Collaboration, R. U. Abbasi, M. Abe +139
The results on ultra-high-energy cosmic rays (UHECR) mass composition obtained with the Telescope Array surface detector are presented. The analysis employs the boosted decision tr…
Lower limit on the ultra-high-energy proton-to-helium ratio from the measurements of the tail of distribution
Ivan S. Karpikov, Grigory I. Rubtsov, Yana V. Zhezher
There are multiple techniques to determine the chemical composition of the ultra-high-energy cosmic rays. While most of the methods are primarily sensitive to the average atomic ma…
