Fornax A, Centaurus A and other radio galaxies as sources of ultra-high
  energy cosmic rays
  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.
