Three components are found in a form of a bright core and two weak jet components showing superluminal motion reaching up to 12.1 h −1 c. [14] There is a jet along the position angle of 69°, made up of a prominent component 15 mas from the core with a diffused structure extending out to 30 mas. [15]
PKS 1830-211 is a gravitationally-lensed blazar in the southern constellation of Sagittarius, one of the most powerful such objects known. [4] It has a high redshift (z) of 2.507, an indicator of its significant distance. [2] This flat-spectrum radio quasar (FSRQ) [3] is one of the brightest extraterrestrial radio sources. [5]
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
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]
Once upon a time, in a far away land called England, a young Prince decided to play for the university water polo team and donned a Speedo that was abnormally high up on his waist.
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 ...
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 ...
