Visible more than half a Universe away, the awesome light emitted by Quasars provides invaluable information about the evolution of the Universe over great swaths of cosmic time. Tracking their evolution provides key insight into the black hole - galaxy correlation and star formation in the early Universe. 

Research in Steward Observatory is focused on observing Quasars at the highest redshifts possible and examining the correlation between black hole growth and galaxy growth across cosmic time.
