Space Physics
Active galactic nuclei (AGNs) are the extremely bright centers of some galaxies, powered by supermassive black holes that actively accrete matter. They emit enormous amounts of energy across the electromagnetic spectrum, often outshining their entire host galaxies. This intense activity is closely related to particle acceleration at shocks, where energetic particles are propelled to near-light speeds, contributing to the diverse phenomena observed in AGNs.
congrats on reading the definition of active galactic nuclei. now let's actually learn it.
