First quasar discovered to be multiply image-lensed by a galaxy cluster and currently the third largest quasar lens with the separation between images of 15″ [5] [6] [7] SDSS J1029+2623 3 Galaxy cluster at z = 0.6 The current largest-separation quasar lens with 22.6″ separation between furthest images [8] [9] [10] SDSS J2222+2745 6 [11]
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.
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 ...
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]
At a distance of more than 13.03 billion light years from Earth, J0313–1806 is the most distant— and thus the most ancient — quasar yet seen by astronomers. Astronomers just detected the ...
This is a list of the largest cosmic structures so far discovered. The unit of measurement used is the light-year (distance traveled by light in one Julian year; approximately 9.46 trillion kilometres). This list includes superclusters, galaxy filaments and large quasar groups (LQGs). The structures are listed based on their longest dimension.
It surpasses the record set by the park’s previous biggest, Hercules, which measured 7.9 centimeters (3.1 inches) and was donated in January 2024. “Hemsworth, he’s different.
Spectrum from quasar HE 0940-1050 after it has travelled through intergalactic medium This view, taken with infrared light, is a false-color image of a quasar-starburst tandem with the most luminous starburst ever seen in such a combination. Quasars also provide some clues as to the end of the Big Bang's reionization.
