Scientific paper

We have decomposed the spectra of over 900 broad-line AGN and host galaxy components using the eigenvector technique of Vanden Berk et al. (2006). We have measured the host galaxy luminosities and velocity dispersions, and estimated central black hole masses from the broad-line AGN spectral components. The host galaxy velocity dispersions and luminosities follow the well-known Faber-Jackson relation (1976). The estimated black hole masses are correlated with both the host luminosities and the stellar velocity dispersions, similar to the relationships found for low-redshift bulge-dominated galaxies.
