An active galactic nucleus (AGN) is a region at the center of a galaxy that emits significant amounts of radiation across the electromagnetic spectrum, from radio waves to X-rays. AGNs are believed to be powered by supermassive black holes that are actively accreting matter, which generates intense radiation and other phenomena.AGNs are classified into several types based on their observed properties, including Seyfert galaxies, quasars, and blazars. Seyfert galaxies are AGNs that emit radiat...
