List of quasars

From Wikipedia, the free encyclopedia

This article contains lists of quasars. More than a million quasars have been observed,[1] so any list on Wikipedia is necessarily a selection of them.

Proper naming of quasars are by Catalogue Entry, Qxxxx±yy using B1950 coordinates, or QSO Jxxxx±yyyy using J2000 coordinates. They may also use the prefix QSR. There are currently no quasars that are visible to the naked eye.

List of quasars

[edit]

This is a list of exceptional quasars for characteristics otherwise not separately listed

Quasar Notes
Twin Quasar Associated with a possible planet microlensing event in the gravitational lens galaxy that is doubling the Twin Quasar's image.
QSR J1819+3845 Proved interstellar scintillation due to the interstellar medium.
CTA-102 In 1965, Soviet astronomer Nikolai S. Kardashev declared that this quasar was sending coded messages from an alien civilization.[2]
CID-42 Its supermassive black hole is being ejected and will one day become a displaced quasar.
TON 618 TON 618 is a very distant and extremely luminous quasar—technically, a hyperluminous, broad-absorption line, radio-loud quasar—located near the North Galactic Pole in the constellation Canes Venatici.

List of named quasars

[edit]

This is a list of quasars, with a common name, instead of a designation from a survey, catalogue or list.

Quasar Origin of name Notes
Twin Quasar From the fact that two images of the same quasar are produced by gravitational lensing.
Einstein Cross From the fact that gravitational lensing of the quasar forms a near perfect Einstein cross, a concept in gravitational lensing.
Triple Quasar From the fact that there are three bright images of the same gravitationally lensed quasar. There are actually four images; the fourth is faint.
Cloverleaf From its appearance having similarity to the leaf of a clover. It has been gravitationally lensed into four images, of roughly similar appearance.
Teacup Galaxy The name comes from the shape of the extended emission, which is shaped like the handle of a teacup. The handle is a bubble shaped by quasar winds or small-scale radio jets. Low redshift, highly obscured type 2 quasar.

List of multiply imaged quasars

[edit]

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
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
RX J1131-1231's quasar 4 RX J1131-1231's elliptical galaxy 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.

List of quasars with apparent superluminal jet motion

This is a list of quasars with jets that appear to be superluminal due to relativistic effects and line-of-sight orientation. Such quasars are sometimes referred to as superluminal quasars.

Quasars that have a recessional velocity greater than the speed of light (c) are very common. Any quasar with z > 1 is receding faster than c, while z exactly equal to 1 indicates recession at the speed of light.[33] Early attempts to explain superluminal quasars resulted in convoluted explanations with a limit of z = 2.326, or in the extreme z < 2.4.[34] The majority of quasars lie between z = 2 and z = 5.

Most distant quasars

[edit]
Artist's conception of the oldest known quasar as of 2021, QSO J0313–1806 existing only ~670 million years after the Big Bang despite its large size.

In 1964 a quasar became the most distant object in the universe for the first time. Quasars would remain the most distant objects in the universe until 1997, when a pair of non-quasar galaxies would take the title (galaxies CL 1358+62 G1 & CL 1358+62 G2 lensed by galaxy cluster CL 1358+62).[55]

In cosmic scales distance is usually indicated by redshift (denoted by z) which is a measure of recessional velocity and inferred distance due to cosmological expansion.
