TeV Observations of Radio Galaxies

Dorit Glawion , LSW
Radio galaxies have emerged as a new very high energy (VHE) gamma-ray emitting source class on the extragalactic sky and started to deepen our understanding of the physical processes and the nature of active galactic nuclei (AGN) in general. Up to now there are six radio galaxies detected at gamma-ray energies above 100 GeV. With their jets not directly pointing towards us (i.e. ”misaligned blazars”), they offer a unique tool to probe into the nature of the fundamental (and often ”hidden”) radiation processes in AGN. The detection of fast flux variability in the TeV energy regime, for example, offers important information for our understanding of particle acceleration in AGN. In this talk I will discuss some of the observational results in the TeV range and the theoretical implications from recent years, including, e.g., the extreme short-term variability as seen in IC 310 and NGC 1275.
