The first true quadruple quasar system was discovered in 2015 at a redshift z = 2.0412 and has an overall physical scale of about 200 kpc (roughly 650,000 light-years). [74] A multiple-image quasar is a quasar whose light undergoes gravitational lensing, resulting in double, triple
Artist's conception of the oldest known quasar as of 2021, QSO J0313–1806 existing only ~670 million years after the Big Bang despite its large size. In 1964 a quasar became the most distant object in the universe for the first time.
Size comparison of the event horizons of the black holes of TON 618 and Phoenix A.The orbit of Neptune (white oval) is included for comparison. As a quasar, TON 618 is believed to be the active galactic nucleus at the center of a galaxy, the engine of which is a supermassive black hole feeding on intensely hot gas and matter in an accretion disc.
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 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 Huge Large Quasar Group, (Huge-LQG, also called U1.27) is a possible structure or pseudo-structure of 73 quasars, referred to as a large quasar group, that measures about 4 billion light-years across.
A large quasar group (LQG) is a collection of quasars (a form of supermassive black hole active galactic nuclei) ... characteristic size: 500 Mpc; longest dimension ...
RX J1131-1231 is a distant, supermassive-black-hole-containing quasar located about 6 billion light years from Earth in the constellation Crater. [1] [2]In 2014, astronomers found that the X-rays being emitted are coming from a region inside the accretion disk located about three times the radius of the event horizon.
APM 08279+5255 is a very distant, broad absorption line quasar located in the constellation Lynx.It is magnified and split into multiple images by the gravitational lensing effect of a foreground galaxy through which its light passes.
