摘要：The vast majority of black hole masses that populate the literature are deduced from scaling relationships. Of these, the relationship between the radius of the broad line region and the luminosity of the AGN (the r−L relationship) is perhaps the most widely used and is based on reverberation mapping experiments of low-redshift AGNs. Recent campaigns at MDM Observatory and Lick Observatory have revised and added several new reverberation measurements, some of which are based on observations of NLS1s. We describe preliminary results from ongoing work to recalibrate the r−L relationship with these new reverberation results and high-resolutionHST imaging. We also briefly describe ongoing work to recalibrate the scaling relationship between the black hole mass and host galaxy bulge luminosity for AGNs, the effects of host galaxy morphology on this relationship, and how the AGN relationship compares to that of the sample of quiescent galaxies with dynamical masses. We also investigate the narrow-line Seyfert 1s relative to the rest of the reverberation sample in the context of these scaling relationships.
