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.
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 ]
DA 193 is a blazar [1] located in the constellation of Auriga. It has a high redshift of 2.365. [2] [3] It was first discovered as an unknown astronomical radio source in 1971 by D.G. MacDonell and A.H. Bridle. [4] This is a low polarized quasar [5] containing a classic homogeneous synchrotron self-absorption spectrum. [6]
An X-ray jet has been discovered in PKS 1127-145 by Chandra X-ray Observatory. [16] With an estimated length of 300 kiloparsecs, this makes the longest one detected so far in any of the high redshift quasars. [17] Advanced CCD Imaging Spectrometer also revealed a complex structure in the X-ray jet from the core with bright knots of different ...
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
Even more amazingly, she told the Washington Post three years ago, her fighter jet was unarmed – it had no missiles. She was to be a kamikaze pilot if necessary. She was to be a kamikaze pilot ...
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.
