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 ]
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 ...
The jet has been found to emit X-rays, up until 0.2 arcseconds from a radio hot spot, which could be in reality a bend of the jet. [ 5 ] 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 ]
A blazar is an active galactic nucleus (AGN) with a relativistic jet (a jet composed of ionized matter traveling at nearly the speed of light) directed very nearly towards an observer. Relativistic beaming of electromagnetic radiation from the jet makes blazars appear much brighter than they would be if the jet were pointed in a direction away ...
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 ...
This blazar was first discovered as a compact astronomical radio source in 1970 by astronomers who were conducting interferometer observations [5] and identified with an optical counterpart in 1984. [6] In addition, the radio spectrum of the source appears flat, making it a flat-spectrum radio quasar (FRSQ). [7] [8]
A regional jet departed Kansas and headed to one of the country’s most congested and complicated flight approaches, just south of the brightly illuminated marble monuments of Washington, DC.
