Active Galactic Nuclei Are More Powerful Than Previously Thought

Active Galactic Nuclei Are More Powerful Than Previously Thought

Powered by supermassive black holes swallowing matter in the centers of galaxies, Active Galactic Nuclei (AGN) are the most powerful compact steady sources of energy in the Universe. The brightest Active Galactic Nuclei have long been known to far outshine the combined light of the billions of stars in their host galaxies. Although the possibility of dust dimming the light from Active Galactic Nuclei has been recognized for a long time, the amount has been considered controversial and was widely believed to be negligible. Now, new research reveals that the energy output of Active Galactic Nuclei has been underestimated by not recognizing the extent to which their light is dimmed by dust and Active Galactic Nuclei (like Quasars and Blazars) are much more powerful than previously thought.
