Red quasars are quasars with optical colors that are redder than normal quasars, thought to be the result of moderate levels of dust extinction within the quasar host galaxy. Infrared surveys have demonstrated that red quasars make up a substantial fraction of the total quasar population.
Quasars, Redshifts and Controversies is a 1987 book by Halton Arp, an astronomer famous for his Atlas of Peculiar Galaxies (1966). [1] Arp argued that many quasars with otherwise high redshift are somehow linked to close objects such as nearby galaxies .
Any quasar with z > 1 is receding faster than c, while z exactly equal to 1 indicates recession at the speed of light. [33] Early attempts to explain superluminal quasars resulted in convoluted explanations with a limit of z = 2.326, or in the extreme z < 2.4. [34] The majority of quasars lie between z = 2 and z = 5.
APM 08279+5255 was initially identified as a quasar in 1998 during an Automatic Plate Measuring Facility (APM) survey to find carbon stars in the galactic halo.The combination of its high redshift (z=3.87) and brightness (particularly in the infrared) made it the most luminous object yet seen in the universe.
It was discovered in X-Ray by Varsha Gupta et al. at the Chandra X-Ray observatory [20] It is also notable for being the first case of a quasar being lensed by an almost face-on spiral galaxy. [21] Galaxy MG1654+1346 features a radio ring. The image in the ring is that of a quasar radio lobe, discovered in 1989 by G.Langston et al. [22]
Quasar HE0450-2958 as imaged by the HST. The quasar is near the center of the image; no obvious host galaxy is seen. Near the top of the image is a strongly disturbed and star-forming galaxy. Near the quasar is a blob of gas that is apparently being ionized by the quasar radiation.
Thor, Tigra, Starfox, Quasar, Moondragon, Photon and Jack of Hearts become the temporary Avengers Infinity squad when they travel into space and encounter a group of cosmic entities called the Infinites. The Infinites have plans to rearrange galaxies (destroying all life in those galaxies in the process) in order to improve the flow of their ...
Quasar, Quasar, Burning Bright is a collection of seventeen scientific essays by American writer and scientist Isaac Asimov. It was the thirteenth of a series of books collecting essays from The Magazine of Fantasy and Science Fiction. These essays were first published between May 1976 and September 1977.
