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:
“Every morning I woke in dread, waiting for the day nurse to go on her rounds and announce from the list of names in her hand whether or not I was for shock treatment, the new and fashionable means of quieting people and of making them realize that orders are to be obeyed and floors are to be polished without anyone protesting and faces are to be made to be fixed into smiles and weeping is a crime.”
—Janet Frame (b. 1924)
“We saw the machinery where murderers are now executed. Seven have been executed. The plan is better than the old one. It is quietly done. Only a few, at the most about thirty or forty, can witness [an execution]. It excites nobody outside of the list permitted to attend. I think the time for capital punishment has passed. I would abolish it. But while it lasts this is the best mode.”
—Rutherford Birchard Hayes (1822–1893)
“We go on multiplying our conveniences only to multiply our cares. We increase our possessions only to the enlargement of our anxieties.”
—Anna C. Brackett (1836–1911)
“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)
