Did you know?
Active galactic nuclei are the most luminous persistent sources of electromagnetic radiation in the universe, and as such can be used as a means of discovering distant objects; their evolution as a function of cosmic time also puts constraints on models of the cosmos. See more An active galactic nucleus (AGN) is a compact region at the center of a galaxy that has a much-higher-than-normal luminosity over at least some portion of the electromagnetic spectrum with characteristics … See more AGN are a candidate source of high and ultra-high energy cosmic rays (see also Centrifugal mechanism of acceleration). See more It is convenient to divide AGN into two classes, conventionally called radio-quiet and radio-loud. Radio-loud objects have emission contributions from both the jet(s) and the lobes … See more During the first half of the 20th century, photographic observations of nearby galaxies detected some characteristic signatures of AGN emission, although there was not yet a … See more For a long time it has been argued that an AGN must be powered by accretion of mass onto massive black holes (10 to 10 times the Solar mass). AGN are both compact and persistently extremely luminous. Accretion can potentially give very efficient … See more There is no single observational signature of an AGN. The list below covers some of the features that have allowed systems to be identified as AGN. • Nuclear … See more Unified models propose that different observational classes of AGN are a single type of physical object observed under different conditions. The currently favoured unified models are 'orientation-based unified models' meaning that they propose that the … See more Web2 Jan 2024 · Starting from the center of the sketch, the supermassive black hole central to the active galactic nucleus can be seen. An accretion disk surrounds the active galactic nucleus, and this matter is being pulled inward towards the black hole (this is called accretion. of the material, hence the name)..
