Multi-Messenger studies of Centaurus A with PAO, HESS and FERMI: does everything fit together?

Presenter: Sergey Ostapchenko (Norwegian University for Science and Technology)

Abstract: γ-ray signatures of hadronic acceleration in Centaurus A are investigated. Using two different models for the generation of ultra-high energy cosmic rays (UHECR) in active galactic nuclei and normalizing the UHECR flux of Centaurus A to the observations of the Pierre Auger Observatory, we calculate the accompanying high energy γ-ray flux in the GeV to TeV range. The predictions are then compared to recent Centaurus A observations by HESS and FERMI and implications of these measurements for the high energy neutrino flux of the source are discussed.
