Detection of ultra high energy cosmic rays and neutrinos with lunar orbital radio telescope
European Physical Journal C: Particles and Fields, 2023 Particle cascades induced by ultra-high-energy (UHE) cosmic rays and neutrinos impacting on the lunar regolith usually radiate Cherenkov radio emissions due to the presence of excess negative charge, which is known as Askaryan effect. Several experiments

Production of high-energy neutrinos in binary-neutron-star merger events [PDF]
EPJ Web of Conferences, 2023 High-energy neutral astrophysical messengers, such as neutrinos and photons, can be produced by the interaction of ultra-high-energy cosmic rays (UHECRs) with radiation fields, either during extragalactic propagation or within source environments ...

Search for ultra-high energy photons by complex data of the Yakutsk array [PDF]
EPJ Web of Conferences, 2019 Complex analysis of the Yakutsk array data in order to find air showers produced by photons with energy ≥1018 eV is carried out. On the basis of simulations and experimental data, selection criteria are formed and air showers with characteristics close ...

SLAC T-510: Radio emission from particle cascades in the presence of a magnetic field
EPJ Web of Conferences, 2017 Cosmic ray induced particle cascades radiate in radio frequencies in the Earth’s atmosphere. Geomagnetic and Askaryan emission provide an effective way to detect ultra-high energy cosmic rays.

On parton distributions in a photon gas
, 2009 In some cases it may be useful to know parton distributions in a photon gas. This may be relevant, e.g., for the analysis of interactions of high energy cosmic ray particles with the cosmic microwave background radiation.

Gamma-Ray Bursts, Ultra High Energy Cosmic Rays, and Cosmic Gamma-Ray Background [PDF]
, 1999 We argue that gamma-ray bursts (GRBs) may be the origin of the cosmic gamma-ray background radiation observed in GeV range. It has theoretically been discussed that protons may carry a much larger amount of energy than electrons in GRBs, and this large ...

Ultra-high energy cosmic rays threshold in Randers-Finsler space
, 2008 Kinematics in Finsler space is used to study the propagation of ultra high energy cosmic rays particles through the cosmic microwave background radiation. We find that the GZK threshold is lifted dramatically in Randers-Finsler space.
