Scaling relations between central black hole (BH) mass and host galaxy properties are of
fundamental importance to studies of BH and galaxy evolution throughout cosmic time. Here …

We present an updated and revised analysis of the relationship between the Hβ broad-line
region (BLR) radius and the luminosity of the active galactic nucleus (AGN). Specifically, we …

We present a sample of 151 dwarf galaxies (10 8.5≲ M⋆≲ 10 9.5 M☉) that exhibit optical
spectroscopic signatures of accreting massive black holes (BHs), increasing the number of …

Abstract The AGN Black Hole Mass Database is a compilation of all published spectroscopic
reverberation-mapping studies of active galaxies. We have created a public Web interface …

The focusing optics of NuSTAR have enabled high signal-to-noise ratio spectra to be
obtained from many X-ray bright active galactic nuclei (AGN) and galactic black hole …

According to the virial theorem, all gravitational systems in equilibrium sit on a plane in the
three-dimensional parameter space defined by their mass, size, and second moment of the …

The radius–luminosity () relationship of active galactic nuclei (AGNs) established by the
reverberation mapping (RM) observations has been widely used as a single-epoch black …

We present dynamical modelling of the broad-line region (BLR) for a sample of five Seyfert 1
galaxies using reverberation mapping data taken by the Lick AGN Monitoring Project in …

Supermassive black holes reside at the centers of most, if not all, massive galaxies: the
difference between active and quiescent galaxies is due to differences in mass accretion …

We present the results of a dust reverberation survey for 17 nearby Seyfert 1 galaxies, which
provides the largest homogeneous data collection for the radius of the innermost dust torus …
