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 ...
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 ]
4C +28.07 is a blazar [1] located in the constellation of Aries. It has a redshift of 1.213 [2] [3] and was first discovered in 1970 as a compact astronomical radio source during an interferometer observation and designated as CTD 20. [4] The radio spectrum of the source is considered flat, making it a flat-spectrum radio quasar.
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]
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.
A multiple-image quasar is a quasar whose light undergoes gravitational lensing, resulting in double, triple or quadruple images of the same quasar. The first such gravitational lens to be discovered was the double-imaged quasar Q0957+561 (or Twin Quasar) in 1979. [75]
TXS 0506+056 is a very high energy blazar – a quasar with a relativistic jet pointing directly towards Earth – of BL Lac-type. [3] With a redshift of 0.3365 ± 0.0010, [3] it has a luminosity distance of about 1.75 gigaparsecs (5.7 billion light-years). [4]
PKS 0405–385 is a blazar [5] in the constellation of Eridanus. This is a compact radio quasar with a redshift (z) of 1.285, an indicator of its significant distance. [ 6 ] The radio spectrum of this source appears flat, making it a flat-spectrum radio quasar (FSRQ).
