Give an account of what an AGN is. AGN stands for Active Galactic Nucleus. An AGN is a compact region at the center of a host galaxy which is extremely luminous across the entire electromagnetic spectrum. The host galaxy of an AGN is referred to as an active galaxy. The radiation given off by an AGN in the radio, infrared, visible, ultra-violet, X-ray and/or gamma ray wavebands are believed to come from the accretion disc of the supermassive black hole at the center of the host galaxy.
