Implications of a Cosmogenic Origin of KM3-230213A for Ultra-High-Energy Protons
A. R. Alhebsi, Arjen van Vliet, Domenik Ehlert +1
A significant neutrino event with an estimated energy between and was recently observed by the KM3NeT experiment (KM3-230213A). When interpre…

Ultra-high-energy cosmic rays from ultra-fast outflows of active galactic nuclei
Domenik Ehlert, Foteini Oikonomou, Enrico Peretti
We investigate ultra-fast outflows (UFOs) in active galactic nuclei (AGN) as potential sources of ultra-high-energy cosmic rays (UHECRs). We focus on cosmic-ray nuclei, an aspect n…

Constraints on the proton fraction of cosmic rays at the highest energies and the consequences for cosmogenic neutrinos and photons
Domenik Ehlert, Arjen van Vliet, Foteini Oikonomou +1
Over the last decade, observations have shown that the mean mass of ultra-high-energy cosmic rays (UHECRs) increases progressively toward the highest energies. However, the precise…
