WebApr 11, 2024 · Summary. Both active galactic nuclei and quasars derive their energy from material falling toward, and forming a hot accretion disk around, a massive black hole. … WebApr 6, 2024 · Astronomers have discovered more than 100 double quasars in merging galaxies so far. However, none of them is as old as the two double quasars in this study. The Hubble images show that quasars within each pair are only about 10,000 light-years apart. By comparison, our Sun is 26,000 light-years from the supermassive black hole in the … WebQuasars (short for "quasi-stellar radio source") were one of the first point-like radio sources to be discovered. Quasars' extreme redshift led us to conclude that they are distant active galactic nuclei, believed to be powered by black holes. Active galactic nuclei have jets of charged particles which emit synchrotron radiation. rock induction 2017

A quasar is an extremely luminous active galactic nucleus (AGN). It is pronounced /ˈkweɪzɑːr/ KWAY-zar, and sometimes known as a quasi-stellar object, abbreviated QSO. This emission from an AGN is powered by a supermassive black hole with a mass ranging from millions to tens of billions of solar masses, … See more The term "quasar" was first used in an article by astrophysicist Hong-Yee Chiu in May 1964, in Physics Today, to describe certain astronomically puzzling objects: So far, the clumsily long name "quasi-stellar radio … See more It is now known that quasars are distant but extremely luminous objects, so any light that reaches the Earth is redshifted due to the metric expansion of space. Quasars inhabit the centers of active galaxies and are among the most luminous, powerful, … See more The taxonomy of quasars includes various subtypes representing subsets of the quasar population having distinct properties. See more A grouping of two or more quasars on the sky can result from a chance alignment, where the quasars are not physically associated, from actual physical proximity, or from the effects … See more Background Between 1917 and 1922, it became clear from work by Heber Curtis, Ernst Öpik and others that some objects ("nebulae") seen by astronomers were in fact distant galaxies like the Milky Way. But when radio astronomy began … See more More than 750,414 quasars have been found (as of August 2024), most from the Sloan Digital Sky Survey. All observed quasar spectra have … See more Because quasars are extremely distant, bright, and small in apparent size, they are useful reference points in establishing a measurement grid … See more WebThe name "quasars" started out as short for "quasi-stellar radio sources" (here "quasi-stellar" means "sort of like stars"). The discovery of radio sources that appeared point-like, just like stars, came with the use of surplus World War II radar equipment in the 1950s.

A quasar is a type of active galactic nucleus (AGN), which is a region at the center of a galaxy that emits a tremendous amount of energy. This energy is produced by the accretion of matter onto a supermassive black hole (SMBH) at the center of the AGN.

"WebA blazar is an active galactic nucleus (AGN) with a relativistic jet (a jet composed of ionized matter traveling at nearly the speed of light) directed very nearly towards an observer. Relativistic beaming of electromagnetic radiation from the jet makes blazars appear much brighter than they would be if the jet were pointed in a direction away ... " - Quasar like active galactic
