M 87 and Centaurus A: Laboratories for VHE physics of jets and near supermassive black holes

In the recent years radio-galaxies have emerged as a new class of extragalactic very-high energy γ-ray emitters (VHE; E > 100 GeV). Their proximity and well studied multi-wavelength behavior enable unique studies of the physics of relativistic plasma jets and the immediate surroundings of super-massive black holes. Here, the two most prominent and nearby sources - Centaurus A and M 87 - are presented and their VHE properties are discussed. Special attention is given to the location of the VHE emission, where recent observational results from a joined multi-wavelength campaign on M 87 can offer new insights.
