What Does AGN Stand For?
AGN stands for Active Galactic Nucleus
Active Galactic Nucleus (AGN) refers to the central region of a galaxy that is extraordinarily bright due to the presence of a supermassive black hole surrounded by an accretion disk. This area emits vast amounts of energy across the electromagnetic spectrum, including radio, optical, ultraviolet, and X-rays. AGNs are important for understanding galaxy evolution, as their outflows and radiation can influence star formation and the surrounding intergalactic medium. They come in various types, including quasars, Seyfert galaxies, and blazars, each characterized by different levels of brightness and activity.
