Plasma Physics
Active Galactic Nuclei (AGN) are extremely luminous regions at the centers of some galaxies, powered by supermassive black holes accreting material. These regions emit massive amounts of energy across the electromagnetic spectrum, including radio, optical, ultraviolet, and X-rays, making them key players in the study of cosmic phenomena. AGN are important because they influence the evolution of their host galaxies and play a significant role in cosmic ray acceleration and propagation.
congrats on reading the definition of Active Galactic Nuclei. now let's actually learn it.
