Active Galactic Nuclei Very small angular size: point like High luminosity: compared to host galaxies Broad-band continuum emission: radio to TeV Strong.
Active Galactic Nuclei. Types of Active Galaxies 4 main types –Seyfert galaxies –Radio galaxies –Quasars –Blazars.

Key points: Active Galactic Nuclei: powerful energy sources in “nuclei” (very center) of some galaxies Main types: Seyferts, radio galaxies and quasars.
