WebFeb 24, 2024 · Quasars are part of a class of objects known as active galactic nuclei (AGN). Other classes include Seyfert galaxies and blazars. All three require supermassive black holesto power them. WebBlazars are much rarer than quasars. As of 2024, more than 750,000 quasars have been found. However, only 66 blazars have been identified. The brightest quasar has a maximum absolute magnitude of -26.7, whereas the brightest blazar has a maximum absolute magnitude of -31.4, making them one of the brightest gamma-ray sources in the sky.

WebBlazars are highly active nuclei of distant galaxies. They produce synchrotron-emitting relativistic jets on scales of less than a parsec to many Kpc. When viewed head-on, as opposed to in the plane of the sky, the jet motion appears superluminal, and the emission is Doppler boosted.
