The Black Hole Mass - Spheroid Luminosity relation
The differing Mbh-L relations presented in McLure & Dunlop, Marconi & Hunt and Erwin et al. have been investigated. A number of issues have been identified and addressed in each of these studies, including but not limited to: the removal of a dependency on the Hubble constant; a correction for dust attenuation in the bulges of disc galaxies; the identification of lenticular galaxies previously ...
متن کاملSupermassive Black Hole Mass Functions at Intermediate Redshifts from Spheroid and AGN Luminosity Functions
Redshift evolution of supermassive black hole mass functions (BHMFs) is investigated up to z ∼ 1. BHMFs at intermediate redshifts are calculated in two ways. One way is from early-type galaxy luminosity functions (LFs); we assume an MBH − Lsph correlation at a redshift by considering a passive evolution of Lsph in the local relationship. The resultant BHMFs (spheroid-BHMFs) from LFs of red sequ...
متن کاملThe Relation between Black Hole Mass, Bulge Mass, and Near-infrared Luminosity
We present new accurate near-infrared (NIR) spheroid (bulge) structural parameters obtained by twodimensional image analysis for all galaxies with a direct black hole (BH) mass determination. As expected, NIR bulge luminosities Lbul and BH masses are tightly correlated, and if we consider only those galaxies with secure BH mass measurement and accurate Lbul (27 objects), the spread of MBH-Lbul ...
متن کاملThe black hole mass – galaxy age relation
We present evidence that there is a significant correlation between the fraction of a galaxy’s mass that lies in its central black hole and the age of the galaxy’s stellar population. Since the absorption line indices that are used to estimate the age are luminosity weighted, they essentially measure the time since the last significant episode of star formation in the galaxy. The existence of t...
متن کاملOn the black-hole mass – radio luminosity relation for flat-spectrum radio-loud quasars
A new analysis of the connection between black-hole mass and radio luminosity in radioselected flat-spectrum quasars (FSQ) is presented. In contrast to recent claims in the literature, we find no evidence that the black-hole masses of radio-selected FSQ are systematically lower that those of luminous optically-selected radio-loud quasars. The black-hole masses of the FSQ are estimated via the v...
