Quasi-Stellar Radio Sources or quasars are a variety of galaxies with an active black hole which accrete so much matter that they are brighter than anything in the observable universe by far. However, it is still unclear why these galaxies are generating so much energy.

​

The purpose of the study is to determine whether the local environment (nearby galaxies) of these quasars play a role in powering these galaxies. This was done by viewing raw images of quasars taken by the Hubble Space Telescope using a computer software called DS9. The distances of these nearby objects were recorded, along with their celestial coordinates, their apparent disturbances, and their apparent galaxy types.
