From spectroscopic point of view Seyfert galaxies (as other Active Galactic Nuclei - AGN) basically are subdivided into two types: with and without broad permitted emission lines in their optical spectra (so called type I and type II Seyfert galaxies or AGNs). One of the most fundumental idea concer...
