blazar
/ ²ú±ôÄå′³úä°ù′ /
- An extremely bright, starlike object characterized by rapid changes in luminosity and a flat spectrum. Originally thought to be ordinary irregular variable stars , their spectral properties now lead astronomers to consider blazars as a class of active galactic nuclei . Blazars emit radiation over a very wide range of frequencies, from radio to gamma rays, with their jets pointed at the observer. This orientation accounts for their peculiar properties, specifically the variability and intensity of their brightness, and it also distinguishes blazars from another class of active galactic nucleus, quasars.
Example Sentences
They constructed weekly binned light curves and utilized a Bayesian algorithm, finding that their sample was dominated by blazars with low flare duty cycles and energy fractions.
These can be quite volatile, such as blazars, which are AGN that shoot out jets of ionized matter traveling at nearly the speed of light.
Scientists have long sought to understand how the jets launched from blazars become so luminous and the behavior of the particles in them.
It’s a similar process to what powers a blazar, but lasts just a few months.
The other important component of multimessenger astronomy is the detection of neutrinos, which are emitted alongside electromagnetic radiation from astrophysical objects such as blazars.
