QSO J0313−1806 [2] was the most distant, and hence also the oldest known quasar at z = 7.64, at the time of its discovery. [1] In January 2021, it was identified as the most redshifted (highest z) known quasar, with the oldest known supermassive black hole (SMBH) at (1.6 ± 0.4) × 10 9 solar masses.
The redshift of J0529-4351 is 3.962. The object itself is classified as a radio-quiet quasar.Fitting accretion models to the spectra yields an accretion rate of matter onto the black hole of 280 to 490 solar masses per year for an accretion disk around the black hole observed at an angle of zero to 60 degrees, with accretion occurring near the Eddington limit.
CTA 102, also known by its B1950 coordinates as 2230+114 (QSR B2230+114) and its J2000 coordinates as J2232+1143 (QSO J2232+1143), is a blazar-type quasar discovered in the early 1960s by a radio survey carried out by the California Institute of Technology. [3]
The ULAS J1342+0928 quasar is located in the Boötes constellation. [3] The related supermassive black hole is reported to be "780 million times the mass of the Sun". [5] At its discovery, it was the most distant known quasar. In 2021 it was eclipsed by QSO J0313-1806 as the most distant quasar. [8]
RX J1131-1231 is the name of the complex, quasar, host galaxy and lensing galaxy, together. The quasar's host galaxy is also lensed into a Chwolson ring about the lensing galaxy. The four images of the quasar are embedded in the ring image. Cloverleaf: 4 [3] Brightest known high-redshift source of CO emission [4] QSO B1359+154: 6
3C 279 (also known as 4C–05.55, NRAO 413, and PKS 1253–05) is an optically violent variable quasar (OVV), which is known in the astronomical community for its variations in the visible, radio and X-ray bands. [2] The quasar was observed to have undergone a period of extreme activity from 1987 until 1991. [3]
The quasar's designation, S5, is from the Fifth Survey of Strong Radio Sources, 0014+81 was its coordinates in epoch B1950.0. It also has the other designation 6C B0014+8120, [ 1 ] from the Sixth Cambridge Survey of Radio Sources by the University of Cambridge .
The game of Quasar was created by inventor Geoff Haselhurst around 1987 in Perth, Australia. The original system was sold to Irish investors in 1991. The name Quasar is still in use in the UK and Ireland, but due to trouble securing the name Quasar in other countries, the courier company was renamed Q-ZAR for worldwide operations.
