Active galaxies are those that demonstrate particularly energetic and active nuclei at their centers. These would include Seyfert galaxies with their dust rings and Radio galaxies with their large lobes of radio emissions. There are a couple of other mentionable galaxies such as Blazars, Quasars and Starburst Galaxies. Much of this activity it associated with supermassive black holes that reside at the center of these galaxies. We will discuss these galaxy types and also include an exploration of how galaxies are distributed across the universe.
