Accretion onto Supermassive Black Holes in Quasars: Learning from Optical/UV Observations
Paola Marziani, Deborah Dultzin-Hacyan, Jack W. Sulentic
Accretion processes in quasars and active galactic nuclei are still poorly understood, especially as far as the connection between observed spectral properties and physical paramet…

VLT/ISAAC Spectra of the H-beta Region in Intermediate-Redshift Quasars II. Black Hole Mass and Eddington Ratio
J. W. Sulentic, P. Repetto, G. M. Stirpe +3
We derive black hole masses for a sample of about 300 AGNs in the redshift range 0 < z < 2.5. We use the same virial velocity measure (FWHM Hbeta broad component) for all sources w…
