First: #blazars are galaxies in which the activity of the central supermassive black hole (BH) produces plasma jets moving at the speed of light, randomly pointing towards the observer (us, in this case). So if we detect a blazar in the sky

What “blazars” means
WikipediaA 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 from Earth. Blazars are powerful sources of emission across the electromagnetic spectrum and are observed to be sources of high-energy gamma ray photons
