Scientific Highlights from Observations of Active Galactic Nuclei with the MAGIC Telescope

Since 2004, the MAGIC γ‐ray telescope has newly discovered 6 TeV blazars. The total set of 13 MAGIC‐detected active galactic nuclei includes well‐studied objects at other wavelengths like Markarian 501 and the giant radio galaxy M 87, but also the distant the flat‐spectrum radio quasar 3C 279, and the newly discovered TeV γ‐ray emitter S5 0716+71. In addition, also long‐term and multi‐wavelength studies on well‐known TeV blazars and systematic searches for new TeV blazars have been carried out. Here we report selected highlights from recent MAGIC observations of extragalactic TeV γ‐ray sources, emphasizing the new physics insights MAGIC was able to contribute.
