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 ]
DA 193 is a blazar [1] located in the constellation of Auriga. It has a high redshift of 2.365. [2] [3] It was first discovered as an unknown astronomical radio source in 1971 by D.G. MacDonell and A.H. Bridle. [4] This is a low polarized quasar [5] containing a classic homogeneous synchrotron self-absorption spectrum. [6]
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]
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 ...
Here's how we imagine the most perfect Oktoberfest feast: First things first, make sure to grab plenty of steins to fill to the brim with all your favorite German beers (like a Hefeweizen, Marzen ...
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.
After weeks of icy temperatures in the region, Wednesday night felt comparatively balmy. Jimmy Mazel, 17, and his girlfriend decided to eat dinner at Gravelly Point Park in Arlington, Virginia.
