Twin Quasar: 1979 Lensed into 2 images The lens is a galaxy known as YGKOW G1: First quasar found with a jet with apparent superluminal motion 3C 279: 1971 [25] [26] [27] First quasar found with the classic double radio-lobe structure 3C 47: 1964 First quasar found to be an X-ray source 3C 273: 1967 [39] First "dustless" quasar found
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. Given its observed redshift of 2.219, the light travel time of TON 618 is estimated to be approximately 10.8 billion years.
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.
Discovered through gamma-ray burst mapping. Largest-known regular formation in the observable universe. [8] Huge-LQG (2012–2013) 4,000,000,000 [9] [10] [11] Decoupling of 73 quasars. Largest-known large quasar group and the first structure found to exceed 3 billion light-years. "Giant Arc" (2021) 3,300,000,000 [12] Located 9.2 billion light ...
OQ 172 (OHIO Q 172) is a quasar [1] located in the constellation of Boötes. It has a redshift of (z) 3.544, [2] making it one of the most distant quasars at the time of its discovery by astronomers in 1973. [3] This object was the record holder for almost a decade, before being surpassed by PKS 2000-330 in 1982 located at the redshift of (z) 3 ...
UHZ1 is a background galaxy containing a quasar. At a redshift of approximately 10.1, UHZ1 is at a distance of 13.2 billion light-years, seen when our universe was about 3 percent of its current age. [1] [2] This redshift made it the most distant, and therefore earliest known quasar in the observable universe as of 2023.
The Chandra X-ray image is of the quasar PKS 1127-145, a highly luminous source of X-rays and visible light about 10 billion light-years from Earth. An enormous X-ray jet extends at least a million light-years from the quasar. Image is 60 arcseconds on a side. RA 11h 30m 7.10s Dec −14° 49' 27" in Crater. Observation date: May 28, 2000 ...
Ton 618 (this quasar has possibly the biggest black hole ever found, estimated at 66 billion solar masses) [1] 3C 371; 4C +37.11 (this radio galaxy is believed to have binary supermassive black holes) [2] AP Lib; S5 0014+81 (said to be a compact hyperluminous quasar, estimated at 40 billion solar masses) [3]
