Many galaxies have very bright nuclei, so bright that the central region can be more luminous than the remaining galaxy light. These nuclei are called active galactic nuclei, or AGN for short. Much of the energy output of AGNs is of a non-thermal (non-stellar) type of emission, with many AGN being strong emitters of X-rays, radio and ultravioletradiation, as well as optical radiation. AGN can vary in luminosity on short (hours or days) timescales.

Active galactic nucleus (AGN), small region at the centre of a galaxy that emits a prodigious amount of energy in the form of radio, optical, X-ray, or gamma radiation or high-speed particle jets. Many classes of “active galaxies” have been identified—for example, quasars, radio galaxies, and Seyfert galaxies.
