RX 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 [3] Brightest known high-redshift source of CO emission [4] QSO B1359+154: 6
3C 273 is a quasar located at the center of a giant elliptical galaxy in the constellation of Virgo. It was the first quasar ever to be identified and is the visually brightest quasar in the sky as seen from Earth, with an apparent visual magnitude of 12.9. [2] The derived distance to this object is 749 megaparsecs (2.4 billion light-years).
Artist's impression of QSO J0439+1634. Note the prominent blue hue. QSO J0439+1634, [4] often referred to by just its coordinates, J0439+1634 or J043947.08+163415.7, [1] is a superluminous quasar, and was, until 20 February 2024, (when it was superseded by QSO J0529-4351) considered the brightest quasar in the early universe with a redshift of z = 6.51.
PKS 0537-286 (referred to QSO 0537-286), also known as QSO B0537-286, is a quasar located in the constellation Columba. With a redshift of 3.104, the object is located 11.4 billion light years away [1] and belongs to the flat spectrum radio quasar blazar subclass (FSQR). [2] It is one of the most luminous known high-redshift quasars. [3]
APM 08279+5255 was initially identified as a quasar in 1998 during an Automatic Plate Measuring Facility (APM) survey to find carbon stars in the galactic halo.The combination of its high redshift (z=3.87) and brightness (particularly in the infrared) made it the most luminous object yet seen in the universe.
