Seyfert galaxies are a class of active galactic nuclei (AGN) characterized by intense, broad emission lines in their optical spectra, indicating powerful energy output from a central engine. These sources are believed to be powered by accretion onto a supermassive black hole residing at the center of a host galaxy. The intense radiation and resulting material outflow are generated as matter spirals inward through an accretion disk, creating distinct spectral signatures. The classification relies on the spectroscopic properties of these outflows and is a vital tool for studying the relationship between galactic structure and the dynamics of supermassive black holes in the distant universe.
