[276] Heart of the Quasar — An illustration by Don Dixon depicting the core of a quasar, featuring a supermassive black hole at the center of an active galactic nucleus. The scene illustrates the dynamics of a massive accretion disk where gas and dust spiral inward, becoming superheated and emitting intense radiation before reaching the event horizon. Perpendicular to the disk, a high-energy relativistic jet of ionized matter is being ejected into intergalactic space at near-light speeds. This traditional acrylic on board painting was created in 1988 and has been published in various astronomical journals and textbooks to visualize the Unified Model of Active Galactic Nuclei.
