    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 ]

    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 CLASS B1359 ...

    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).

    TON 618 (abbreviation of Tonantzintla 618) is a hyperluminous, broad-absorption-line, radio-loud quasar, and Lyman-alpha blob [2] located near the border of the constellations Canes Venatici and Coma Berenices, with the projected comoving distance of approximately 18.2 billion light-years from Earth.

    Even accounting for the magnification, the quasar is an extremely powerful object, with a luminosity of 10 14 to 10 15 times the luminosity of the sun. [6] Subsequent observations with the Hubble Space Telescope Imaging Spectrograph confirmed the presence of a third faint image between the two brighter images. Each component has the same ...

    This suggests the quasar is currently undergoing an intense wave of star formations thus increasing its luminosity. [3] A radio jet has also been found on the side of quasar according to a study published in 2023. [5] CCD image of the Cloverleaf quasar taken in March 1988 by the ESO/MPI 2.2m telescope. The four separated images are part of the ...

    RX J1131-1231 is a distant, supermassive-black-hole-containing quasar located about 6 billion light years from Earth in the constellation Crater. [1] [2]In 2014, astronomers found that the X-rays being emitted are coming from a region inside the accretion disk located about three times the radius of the event horizon.
