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 .

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 ...
PKS 1510-089 is a blazar [1] located in the constellation of Libra, categorized as a highly polarized quasar [2] showing fast variations in polarization angles, [3] with a redshift of (z) 0.361. [4] It was first discovered in 1966 as an astronomical radio source during the Parkes Observatory survey in 1966.
Between September 11 and 30 in 2008, the quasar brightened upon showing a flare, with increased magnitudes in both B-band and R-band. [10] In the gamma ray lightcurve, it showed a variable flux reaching a factor of 6 on timescales of weeks. [11] A major gamma ray flare was detected in PKS 0208-512 between November 2019 and May 2020.
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 ]
Artist's rendering of the accretion disc in ULAS J1120+0641, a very distant quasar containing a supermassive black hole with a mass two billion times that of the Sun [1] The Chandra X-ray image is of the quasar PKS 1127-145, a highly luminous source of X-rays and visible light about 10 billion light-years from Earth. An enormous X-ray jet ...
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 ...
