A Comprehensive Hadronic Code Comparison for Active Galactic Nuclei
Matteo Cerruti, Annika Rudolph, Maria Petropoulou +14
We perform the first dedicated comparison of five hadronic codes (AM, ATHEA, B13, LeHa-Paris, and LeHaMoC) that have been extensively used in modeling of the spectral energ…
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…
Ideas and Requirements for the Global Cosmic-Ray Observatory (GCOS)
Markus Ahlers, Ingo Allekotte, Jaime Alvarez-Muniz +136
After a successful kick-off meeting in 2021. two workshops in 2022 and 2023 on the future Global Cosmic-Ray Observatory (GCOS) focused mainly on a straw man design of the detector…
GRANDlib: A simulation pipeline for the Giant Radio Array for Neutrino Detection (GRAND)
GRAND Collaboration, Rafael Alves Batista, Aurélien Benoit-Lévy +112
The operation of upcoming ultra-high-energy cosmic-ray, gamma-ray, and neutrino radio-detection experiments, like the Giant Radio Array for Neutrino Detection (GRAND), poses signif…
High-energy neutrino transients and the future of multi-messenger astronomy
Claire Guépin, Kumiko Kotera, Foteini Oikonomou
The recent discovery of high-energy astrophysical neutrinos and first hints of coincident electromagnetic and neutrino emission herald the beginning of the era of multi-messenger a…
Multi-messenger signature of cosmic rays from the microquasar V4641 Sgr propagating along a Galactic Magnetic Field line
Andrii Neronov, Foteini Oikonomou, Dmitri Semikoz
The recently detected extended, very-high-energy gamma-ray emission from the microquasar V4641 Sgr reveals a puzzling 200-parsec-long jet-like structure significantly misaligned wi…
