While characterization of the MBH–σ* relationship in AGNs has improved due to the increase in available data and the improvement in accuracy of both MBH and σ* measurements, additional data at the high-luminosity end of the distribution of quasars are needed, as recent studies indicate that perhaps the relation steepens in this regime. To this end, we present three new measurements in objects at the high-luminosity end of the relation.
