Bright Cosmic-Ray Source as a Solution to Auger-TA Tensions
Alexander Korochkin, Dmitri Semikoz, Peter Tinyakov
The ultra-high-energy cosmic ray (UHECR) spectra measured by the Pierre Auger Observatory (Auger) and the Telescope Array (TA) agree very well below eV but differ signi…
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…
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…
Images of the Ultra-High Energy Cosmic Rays from Point Sources
K. Dolgikh, A. Korochkin, G. Rubtsov +2
Our latest paper investigates the effects of UHECR propagation in a turbulent intergalactic magnetic field in the small-angle scattering regime, specifically focusing on the non-tr…
Caustic-like Structures in UHECR Flux after Propagation in Turbulent Intergalactic Magnetic Fields
K. Dolgikh, A. Korochkin, G. Rubtsov +2
UHECR propagation in a turbulent intergalactic magnetic field in the small-angle scattering regime is well understood for propagation distances much larger than the field coherence…
A lower bound on intergalactic magnetic fields from time variability of 1ES 0229+200 from MAGIC and Fermi/LAT observations
MAGIC Collaboration, V. A. Acciari, I. Agudo +206
Extended and delayed emission around distant TeV sources induced by the effects of propagation of gamma rays through the intergalactic medium can be used for the measurement of the…
Detectability of large correlation length inflationary magnetic field with Cherenkov telescopes
Alexander Korochkin, Andrii Neronov, Guilhem Lavaux +2
Magnetic fields occupying the voids of the large scale structure may be a relic from the Early Universe originating from either Inflation or from cosmological phase transitions. We…
Search for spectral features in extragalactic background light with gamma-ray telescopes
A. Korochkin, A. Neronov, D. Semikoz
Cumulative optical and infrared emission from galaxies accumulated over cosmological time scales, the extragalactic background light (EBL), could be probed by complementary techniq…
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…
