WebActive Galactic Nuclei (AGN): Active nuclei are common to galaxies in the early universe. AGN have diverse observed properties, but most of these can described by a single unified model. The unified model consists of a supermassive black hole with a superheated accretion disk that radiates in the optical through soft X-ray. WebSep 1, 1993 · Abundances do not depend significantly on the age of quasars. The nuclear metallicity may be rapidly generated and maintained at approximately time-stationary values. We review two mechanisms proposed for the metallicity enrichment of quasars and, in general, all active galactic nuclei (AGN).

WebApr 23, 2012 · Our result implies that the metallicity plays an important role in the formation of quasar outflows, likely via affecting outflow acceleration. This effect may have a profound impact on galaxy evolution via momentum feedback and chemical enrichment.
