Web17 aug. 2024 · Active galactic nuclei, or AGN for short, are galaxies with extraordinarily luminous cores powered by black holes containing millions or even billions of times more material than our Sun. As gas is trapped by a monster black hole's gravity, it settles into an accretion disk and starts to spiral down the Universe's ultimate drain. 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.
