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 |

“Thirty—the promise of a decade of loneliness, a thinning list of single men to know, a thinning brief-case of enthusiasm, thinning hair.”
—F. Scott Fitzgerald (1896–1940)
“Shea—they call him Scholar Jack—
Went down the list of the dead.
Officers, seamen, gunners, marines,
The crews of the gig and yawl,
The bearded man and the lad in his teens,
Carpenters, coal-passers—all.”
—Joseph I. C. Clarke (1846–1925)
“Off south, the bison multiply so fast
a slaughter’s mandatory every spring
and every spring the creeks get fat
and Kicking Horse fills up.”
—Richard Hugo (1923–1982)
“The imaged word, it is that holds
Hushed willows anchored in its glow.
It is the unbetrayable reply
Whose accent no farewell can know.”
