See also: Quasar, List of quasars 3C 454.3 is a blazar (a type of quasar with a jet oriented toward Earth ) located away from the galactic plane . It is one of the brightest gamma ray sources in the sky, [ 2 ] and is one of the most luminous astronomical object ever observed, with a maximum absolute magnitude of -31.4. [ 3 ]
The components of the jet have been found to move by about 0.25–0.42 mas, which at the distance of the jet represent apparent speeds that are 5 to 15 times faster than the speed of light. [6] The radio jet exhibits superluminal motion for 0.12 to 12 mas, with apparent speeds that accelerate from ~5 c to ~15c within 0.3 mas.
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]
PKS 0637-752 is a quasar located six billion light years in the constellation of Mensa. [1] It is noted for having a bright and largest astrophysical jet at redshift of z = 0.651. [ 2 ] [ 3 ] Discovered by Einstein Observatory in 1980 through X-rays, [ 4 ] PKS 0637-752 was the first celestial object to be observed by Chandra X-ray Observatory ...
Twin Quasar: 1979 Lensed into 2 images The lens is a galaxy known as YGKOW G1: First quasar found with a jet with apparent superluminal motion 3C 279: 1971 [25] [26] [27] First quasar found with the classic double radio-lobe structure 3C 47: 1964 First quasar found to be an X-ray source 3C 273: 1967 [39] First "dustless" quasar found
PKS 1830-211 is a gravitationally-lensed blazar in the southern constellation of Sagittarius, one of the most powerful such objects known. [4] It has a high redshift (z) of 2.507, an indicator of its significant distance. [2] This flat-spectrum radio quasar (FSRQ) [3] is one of the brightest extraterrestrial radio sources. [5]
PKS 0458-020 is found variable across the electromagnetic spectrum and a source of gamma ray activity. [7] [8] [9] It is known to show optical flares which was detected by Fermi Gamma-ray Space Telescope (Fermi LAT) [10] and by the Nordic Optical Telescope in September 2012, where it was reported to be 30 times brighter than its daily flux of (E > 100 MeV) when recorded by Fermi LAT. [11]
Observed by the 20-GHz Australia Telescope Compact Array radio survey, [2] PKS 0451-28 is classified as a blazar. [3] [4] It is a type of an active extragalactic object launching out a relativistic astrophysical jet towards the direction of Earth with the observer's line of sight.
