Multi-messenger astronomy with Centaurus A

Understand

We calculated for the nearest active galactic nucleus (AGN), Centaurus A (Cen A), the flux of high energy cosmic rays and of accompanying secondary photons and neutrinos expected from hadronic interactions in the source.

• We used as two basic models for the generation of ultrahigh energy cosmic rays (UHECR) shock acceleration in the radio jet and acceleration in the regular electromagnetic field close to the core of the AGN, normalizing the UHECR flux to the observations of the Auger experiment.
• Here we compare the previously obtained photon fluxes with the recent data reported by the Fermi LAT and H.E.S.S.
• collaborations.
