Quasar Images Lens Notes Twin Quasar: 2 YGKOW G1: First gravitationally lensed object discovered : Triple Quasar (PG 1115+080) 4 Originally discovered as 3 lensed images, the fourth image is faint. It was the second gravitationally lensed quasar discovered. Einstein Cross: 4 Huchra's Lens: First Einstein Cross discovered RX J1131-1231's quasar 4
That list is available at list of quasars. 3C 295: 1960– z=0.461 This is a radio galaxy. This was the remotest object known at time of discovery of its redshift. This was the last non-quasar to hold the title of most distant object known until 1997. In 1964, quasar 3C 147 became the most distant object in the universe known. [76] [83] [97 ...
A multiple-image quasar is a quasar whose light undergoes gravitational lensing, resulting in double, triple or quadruple images of the same quasar. The first such gravitational lens to be discovered was the double-imaged quasar Q0957+561 (or Twin Quasar) in 1979. [ 75 ]
Quasars, though, are on the small end of the supermassive black hole size class—sometimes just a few days across, or about 1,000 of the distance between Earth and the Sun, Space.com explains ...
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]
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.
A team of international astronomers recently announced the largest superstructure in the known universe. The immense structure named "Quipu" is estimated to stretch for an astonishing 1.4 billion ...
