Active Galactic Nuclei, Seyferts & Quasars: Observation, Measurement & Evidence

Active galactic nuclei are extraordinarily luminous galactic centers powered by matter accreting onto supermassive black holes. AGN trace black-hole growth, influence galaxy gas through feedback, illuminate intergalactic material, and provide beacons visible across much of cosmic history.
