Centaurus A at Ultra-High Energies

Abstract

We review the importance of Centaurus A in high energy astrophysics as a nearby object with many of the properties expected of a major source of very high energy cosmic rays and gamma-rays. We examine observational techniques and the results so far obtained in the energy range from 200 GeV to above 100 EeV and attempt to fit those data with expectations of Centaurus A as an astrophysical source from VHE to UHE energies.
