Quasar - Wikipedia The radiant energy of quasars is enormous; the most powerful quasars have luminosities thousands of times greater than that of a galaxy such as the Milky Way [2][3] Quasars are usually categorized as a subclass of the more general category of AGN
List of quasars - Wikipedia List of named quasars This is a list of quasars, with a common name, instead of a designation from a survey, catalogue or list
Quasar - Simple English Wikipedia, the free encyclopedia The energy emitted by a quasar is gravitational energy, created from mass falling onto the accretion disc around the black hole Quasars are extremely luminous They were first identified as being high redshift sources of electromagnetic radiation, including radio waves and visible light
3C 273 - Wikipedia 3C 273 is a quasar located at the center of a giant elliptical galaxy in the constellation of Virgo It was the first quasar ever to be identified and is the visually brightest quasar in the sky as seen from the Earth, with an apparent visual magnitude of 12 9 [2] The derived distance to this object is 749 megaparsecs (2 4 billion light-years) The mass of its central supermassive black hole
Twin Quasar - Wikipedia The Twin Quasar is a single quasar whose appearance is distorted by the gravity of another galaxy much closer to Earth along the same line of sight This gravitational lensing effect is a result of the warping of space-time by the nearby galaxy, as described by general relativity
Quasar (disambiguation) - Wikipedia Quasar (QSR: quasi-stellar radio source; QSO: quasi-stellar object) is an astronomical body producing vast amounts of energy, an energized galactic core Quasar or variant, may also refer to: Quasar Thakore-Padamsee (born 1978), Indian stage actor turned theatre director producer
Large quasar group - Wikipedia A large quasar group (LQG) is a collection of quasars (a form of supermassive black hole active galactic nuclei) that form what are thought to constitute the largest astronomical structures in the observable universe
Hubble Quasars - NASA Science They are distant galaxies whose incredibly bright cores are powered by supermassive black holes Quasars have been found with luminosities between 10 to 100,000 times that of our Milky Way galaxy, generated from an area just a few light-days to a few light-years across
Quasar | Discovery, Structure Evolution | Britannica Quasar, an astronomical object of very high luminosity found in the centres of some galaxies and powered by gas spiraling at high velocity into an extremely large black hole
