List of Multiply Imaged Quasars
This is a list of quasars that as a result of gravitational lensing appear as multiple images on Earth.
| Quasar | Images | Lens | Notes |
|---|---|---|---|
| Twin Quasar | 2 | YGKOW G1 | First gravitationally lensed object discovered Third largest separation between images (6 ″) |
| 2QZ J1435+0008 | 2 | Largest separation between images (33 ″) | |
| 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 |
| RXS J1131-1231's quasar | 4 | RXS J1131-1231's elliptical galaxy | RXS 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 | Brightest known high-redshift source of CO emission | |
| SDSS J1004+411 | 5 | SDSS J1004+4112 | First quasar discovered to be multiply image-lensed by a galaxy cluster Second largest separation between images (15 ″) |
| QSO B1359+154 | 6 | CLASS B1359+154 and three more galaxies | First sextuply-imaged galaxy |

Famous quotes containing the words list of, list, multiply and/or imaged:
“The advice of their elders to young men is very apt to be as unreal as a list of the hundred best books.”
—Oliver Wendell Holmes, Jr. (1841–1935)
“Modern tourist guides have helped raised tourist expectations. And they have provided the natives—from Kaiser Wilhelm down to the villagers of Chichacestenango—with a detailed and itemized list of what is expected of them and when. These are the up-to- date scripts for actors on the tourists’ stage.”
—Daniel J. Boorstin (b. 1914)
“Science and technology multiply around us. To an increasing extent they dictate the languages in which we speak and think. Either we use those languages, or we remain mute.”
—J.G. (James Graham)
“The imaged word, it is that holds
Hushed willows anchored in its glow.
It is the unbetrayable reply
Whose accent no farewell can know.”
—Hart Crane (1899–1932)
