Summary
The central region of Active Galactic Nuclei (AGN) are the main research topic of the group headed by Dr. Anton Zensus. The regions surrounding the nuclear engines (supermassive black holes) are observed using radio interferometry with Very Long Baselines (VLBI). By comparison with observations of AGN in all accessible wavelength ranges, detailed physical models for these most energetic objects in the Universe are made. In addition cosmological questions are investigated, especially questions concerning the cosmic microwave background (CMB).
