The origin of ultra-high energy cosmic rays (UHECRs) is still unknown. It has recently been proposed that UHECR anisotropies can be attributed to starburst galaxies or active galactic nuclei. We suggest that the latter is more likely and that giant-lobed radio galaxies such as Centaurus A and Fornax A can explain the data.

  1. Revisiting Propagation Delays of Ultra-High-Energy Cosmic Rays from Long-lived Sources

    astro-ph.HE 2025-02 conditional novelty 4.0 of 10

    Propagation delays of ultra-high-energy cosmic rays in extragalactic magnetic fields can match or exceed AGN duty cycles, weakening the link between detected cosmic rays and their long-lived sources.
