Figure 24-13: A Unified Model of Active Galaxies The AGN model consists of a supermassive black hole surrounded by an intensely luminous accretion disk. Farther out is a dusty doughnut-shaped torus. A pair of jets is also shown on this object, although not every AGN has jets. While this basic structure is at the heart of the randomly oriented AGN in space, each AGN can appear different depending on the viewing angle.
