Simulation of the Isotropic Ultra-High Energy Photon Flux in the Solar Magnetic Field
Universe, 2022 Both the lack of observation of ultra-high energy (UHE) photons and the limitations of the state-of-the-art methodology being applied for their identification motivate studies on alternative approaches to the relevant simulations and the related ...

The Extragalactic Ultra-high-energy Cosmic-Ray Dipole [PDF]
, 2017 We explore the possibility that the recently detected dipole anisotropy in the arrival directions of >8 EeV ultra-high-energy cosmic-rays (UHECRs) arises due to the large-scale structure.

Secondary GeV-TeV emission from ultra-high-energy cosmic rays accelerated by GRB 221009A [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2022 The origin of ultra-high-energy cosmic rays (UHECRs) remains elusive. Gamma-ray bursts (GRBs) are among the best candidates able to meet the stringent energy requirements needed for particle acceleration to such high energies.

Detection of ultra-high energy cosmic ray air showers by Cosmic Ray Air Fluorescence Fresnel lens Telescope for next generation [PDF]
EPJ Web of Conferences, 2019 In the future, ultra-high energy cosmic ray (UHECR) observatory will be expanded due to the small flux. Then, cost reduction is useful strategy to realize a huge scale observatory.

Ultra high energy cosmic rays from past activity of Andromeda galaxy [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2022 It is shown that the relativistic jets associated with the growth and past activity of the supermassive black hole in the Andromeda galaxy could be the main source of cosmic rays with energies above 1015 eV.

Measurements of very-forward energy with the CASTOR calorimeter of CMS [PDF]
EPJ Web of Conferences, 2019 The very-forward energy production in hadron collisions is of paramount importance for the understanding of ultra-high energy cosmic ray air showers. The CASTOR calorimeter of CMS is located at -6:6 < η < -5:2 in the phase-space where the peak of energy ...

Cosmic ray contribution in extragalactic background gamma-ray emission at an energy of 0.1 TeV
EPJ Web of Conferences, 2017 We estimate the intensity of gamma-quanta at the energy 0.1 TeV that is generated in extragalactic space in interactions of ultra-high energy cosmic rays with the cosmic background emission.

Constraints on direct acceleration of UHECRs in astrophysical sources
EPJ Web of Conferences, 2013 A toy model of the population of numerous non-identical extragalactic sources of ultra-high-energy cosmic rays is presented. In the model, the acceleration of cosmic-ray particles is direct (not diffusive) and takes place in magnetospheres of ...
