Section 4 Title: The Evolution of QSO Spectra Proposal_Category: AR Scientific_Category: Quasars Cycle: 5 Investigators PI_name: Paul Francis PI_Institution: University of Melbourne CoI_Name: Anuradha Koratkar CoI_Institution: Space Telescope Science Institute Contact: ! Y or N (designate at most one contact) Abstract: ! Free format text (please update) Using data from the IUE satellite, it has recently been shown that the emission-lines of radio-quiet QSOs evolve between z=2 and the present, and those of radio-loud QSOs apparently do not. This surprising link between the hitherto disparate mysteries of QSO evolution, radio-loudness and emission-line structure may offer an important clue to all three problems. We propose to use HST archive spectra to confirm this result, and to identify the reason for the spectral evolution. The superior resolution and signal-to-noise ratios of HST spectra will allow us to separate out the evolution of emission and absorption components, the contributions of the narrow and broad-line regions, and to investigate the evolution of weak emission-lines. We will also use high resolution HST images to look for connections between the spectral evolution and the QSO environments. Questions !
