High redshift quasars, emission lines and cloudy

Research output: Contribution to journalArticlepeer-review


I describe some of the outstanding "big picture" questions in quasar research and how the development of the plasma simulation code Cloudy is being guided to answer them. QSO spectra are complex and challenge even the most sophisticated spectral codes. Particular emphasis is given to a central question - how do the properties of the central black hole and the accretion disk are manifested in the observed spectrum.
