This book covers how Active Galactic Nuclei (AGN) are fueled by gas (or stars), how we can account for the wide variety of AGN observed, from Seyfert/Liners to quasars, and for the two types (AGN 1 and 2) either through dust obscuration, and geometrical orientation arguments, or through intrinsic activity difference, qualitative or quantitative.
