Blazars News

Blazars are a very energetic type of active galactic nucleus (AGN), characterized by their intense emissions and rapid variability across the electromagnetic spectrum. These phenomena are powered by supermassive black holes at the centers of massive galaxies, which accrete matter and generate powerful jets of charged particles that travel at nearly the speed of light. What distinguishes blazars from other types of AGNs is that one of these jets is pointed almost directly towards Earth, resulting in a beam of radiation that appears extremely bright due to the relativistic effects of the jet’s high velocity. Blazars are known for their dramatic variability, often changing brightness over timescales ranging from minutes to years. They are also significant sources of gamma rays and are key objects of study in high-energy astrophysics, helping scientists probe the properties of relativistic jets and the environments around black holes.
