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 ...
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 0438-436, also known as PKS J0440-4333, is a quasar located in constellation Caelum.With a high redshift of 2.86, [1] the object is located 11.2 billion light-years from Earth [2] and is classified as a blazar due to its flat-spectrum radio source, [3] (in terms of the flux density as (F v ~ V-a) with α < 0.5 and its optical polarization.
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 ...
PKS 2131-021 is a quasar and a BL Lacerate object, [2] producing an astrophysical jet. [ 3 ] lt is located in the constellation Aquarius and classified as a blazar , a type of active galactic nucleus whose relativistic jet points in the direction towards Earth .
