WebBlazar definition at Dictionary.com, a free online dictionary with pronunciation, synonyms and translation. Look it up now! Blazars are powerful sources of emission across the electromagnetic spectrum and are observed to be sources of high-energy gamma ray photons. Blazars are highly variable sources, often undergoing rapid and dramatic fluctuations in brightness on short timescales (hours to days). See more 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 See more The observed emission from a blazar is greatly enhanced by relativistic effects in the jet, a process called relativistic beaming. … See more Blazars are thought to be active galactic nuclei, with relativistic jets oriented close to the line of sight with the observer. The special jet orientation explains the general peculiar … See more • AAVSO High Energy Network • Blazar Monitoring List, Purdue University • Expanding Gallery of Hires Blazar Images See more Blazars, like all active galactic nuclei (AGN), are thought to be ultimately powered by material falling onto a supermassive black hole at the center of the host galaxy. Gas, … See more Many of the brighter blazars were first identified, not as powerful distant galaxies, but as irregular variable stars in our own galaxy.
