    en.wikipedia.org/wiki/3C_273

    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).

    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

    The first true quadruple quasar system was discovered in 2015 at a redshift z = 2.0412 and has an overall physical scale of about 200 kpc (roughly 650,000 light-years). [74] A multiple-image quasar is a quasar whose light undergoes gravitational lensing, resulting in double, triple

    Each black circle and red cross on the upper image map is a quasar similar to this one. The Huge Large Quasar Group , ( Huge-LQG , also called U1.27 ) is a possible structure or pseudo-structure of 73 quasars , referred to as a large quasar group , that measures about 4 billion light-years across.

    In 1993, Thomson et al. suggested that the (outer) jet of the quasar 3C 273 is nearly collinear to the Earth's line-of-sight. Superluminal motion of up to ~9.6c has been observed along the (inner) jet of this quasar. [5] [6] [7] Superluminal motion of up to 6c has been observed in the inner parts of the jet of M87.

    It is defined in one study as the cluster center. The cluster has a sparse gaseous medium that emits X-rays, lower in temperature toward the middle. [117] The combined mass of the cluster is estimated to be 0.15 to 1.5 × 10 15 M ☉. [127]
