Black Holes of Active and Quiescent Galaxies: I. the Black Hole-bulge Relation Revisited
Massive Black Holes detected in the centers of many nearby galaxies show an approximately linear relation with the luminosity of the host bulge, with the black hole mass being 0.001-0.002 of the bulge mass. Previous work suggested that black holes of active (Seyfert 1) galaxies follow a similar relation, but apparently with a significantly lower value of MBH/Mbulge (Wandel 1999). New data show ...
متن کاملSupermassive Black Holes in Active Galactic Nuclei. I. the Consistency of Black Hole Masses in Quiescent and Active Galaxies
We report the first results of a program to measure accurate stellar velocity dispersions in the bulges of the host galaxies of active galactic nuclei (AGNs) for which accurate black hole (BH) masses have been determined via reverberation mapping. We find good agreement between BH masses obtained from reverberation mapping, and from the M• −σ relation as defined by quiescent galaxies, indicatin...
متن کاملBlack hole masses in active galaxies
This contribution reviews two topics of current interest in the study of black hole demographics in active galaxies: Can the stellar velocity dispersions of quasar host galaxies be measured? And can we constrain the black hole mass function below 10 M ?
متن کاملActive Galaxies and the Study of Black Hole Demographics
We discuss the critical importance of black hole mass indicators based on scaling relations in active galaxies. We highlight outstanding uncertainties in these methods and potential paths to substantial progress in the next decade. 1. BLACK HOLE DEMOGRAPHICS AND ACTIVE GALAXIES The most reliable measures of black hole (BH) mass are derived from spatially resolved dynamical tracers, the stars at...
متن کاملRadio-loudness of Active Galaxies and the Black Hole Evolution
Active galactic nuclei (AGNs) form two distinct sequences on the radio-loudness – Eddington-ratio plane. The ‘upper’ sequence contains radio selected AGNs, the ‘lower’ sequence is composed mainly of optically selected AGNs. The sequences mark the upper bounds for the radio-loudness of two distinct populations of AGNs, hosted respectively by elliptical and disk galaxies. Both sequences show the ...
