"WebThese nuclei are called active galactic nuclei, or AGN for short. Much of the energy output of AGN s is of a non-thermal (non- stellar) type of emission, with many AGN being strong emitters of X-rays, radio and ultraviolet radiation, as well as optical radiation. AGN can vary in luminosity on short (hours or days) timescales. " - Nucleus in astronomy
