Cosmogenic photon fluxes at ultra-high energies
Marcus Niechciol, Chiara Jane Papior, Markus Risse
During their propagation, ultra-high energy cosmic rays produce cosmogenic photons. The expected flux level of these photons may vary by orders of magnitude depending on parameters…

Towards Searching for Photons with Energies beyond the PeV Range from Galactic PeVatrons
Marcus Niechciol, Chiara Papior, Markus Risse
Several gamma-ray observatories have discovered photons of cosmic origin with energies in the PeV () range. Photons at these energies might be produced as by-pr…
