Abstract
The brightest quasars were born 10 billion years ago during the Quasar Epoch. These quasars were bigger and brighter than any of the quasars formed after, and this paper seeks to find out why. Quasars are a type of Active Galactic Nucleus, which is a compact center of a galaxy. The type of galaxy that contains the Active Galactic Nucleus plays an important part in their luminosity, as elliptical galaxies have much brighter Active Galactic Nuclei than spiral galaxies. The reason that Active Galactic Nuclei form in galaxies is because galaxies contain supermassive black holes, since only supermassive black holes may contain an Active Galactic Nucleus. The stars and gas clouds present in galaxies make a bigger accretion disc. This was happening at a large rate during the Quasar Epoch as opposed to now.
