Abstract: AGN afford an opportunity to study the evolution of the black hole – bulge relationship over cosmic time. The mass of the supermassive black hole can be estimated from the width of the broad emission lines in the spectrum or the AGN luminosity. The mass or velocity dispersion of the host galaxy’s bulge may be estimated from the host galaxy luminosity, or from the widths of the narrow optical emission lines or the CO lines. All methods have uncertainties, and the results show substantial inconsistencies. There are indications that black holes at high redshift in optically luminous AGN reside in proportionally smaller host galaxies than today.
