Impact of the finite life-time of UHECR sources
Björn Eichmann, Michael Kachelrieß
The observational data on ultrahigh energy cosmic rays (UHECR), in particular their mass composition, show strong indications for extremely hard spectra of individual mass groups o…
CRPropa 3.2 -- an advanced framework for high-energy particle propagation in extragalactic and galactic spaces
Rafael Alves Batista, Julia Becker Tjus, Julien Dörner +14
The landscape of high- and ultra-high-energy astrophysics has changed in the last decade, largely due to the inflow of data collected by large-scale cosmic-ray, gamma-ray, and neut…
Solving the multi-messenger puzzle of the AGN-starburst composite galaxy NGC 1068
Björn Eichmann, Foteini Oikonomou, Silvia Salvatore +2
Multi-wavelength observations indicate that some starburst galaxies show a dominant non-thermal contribution from their central region. These active galactic nuclei (AGN)-starburst…
Explaining the UHECR spectrum, composition and large-scale anisotropies with radio galaxies
Björn Eichmann, Michael Kachelrieß, Foteini Oikonomou
Radio galaxies are promising candidates as the sources of ultrahigh energy cosmic rays (UHECRs). In this work, we examine if the stringent constraints imposed by the dipole and qua…
