Testing Radiation Pressure Corrections to Reverberation Mapping Masses
نویسنده
چکیده
Multi-epoch reverberation mapping of the Seyfert galaxy, NGC 5548, suggests that radiation pressure is not strongly biasing the black hole (BH) masses derived for active galactic nuclei (AGNs). The model proposed by Marconi et al. to account for radiation pressure in BH mass estimates fails to explain the observations of NGC 5548, the only AGN with reverberation campaigns spanning a sufficiently broad luminosity range to accurately test the model in this way. Future reverberation studies with appropriately chosen targets may improve our understanding of the role radiation pressure plays in the kinematics of the broad-line region.

Simultaneous X-ray/optical/UV snapshots of active galactic nuclei from XMM-Newton: spectral energy distributions for the reverberation mapped sample
We employ contemporaneous optical, UV and X-ray observations from the XMM-Newton EPIC-pn and Optical Monitor (OM) archives to present, for the first time, simultaneous spectral energy distributions (SEDs) for the majority of the Peterson et al. (2004) reverberation mapped sample of active galactic nuclei (AGN). The raw data were reduced using the latest pipelines and are all analysed consistent...
متن کاملSystematic Errors in the Estimation of Black Hole Masses by Reverberation Mapping
The mass of the central black hole in many active galactic nuclei has been estimated on the basis of the assumption that the dynamics of the broad emission line gas are dominated by the gravity of the black hole. The most commonly-employed method is to estimate a characteristic size-scale r∗ from reverberation mapping experiments and combine it with a characteristic velocity v∗ taken from the l...
متن کاملAdvances in Reverberation Mapping
This contribution briefly reviews the reverberation mapping technique which leads to determination of black hole masses. I focus on the emerging relation between the broad-line region size and the active galactic nucleus (AGN) luminosity, and on an overview of recent results of reverberation mapping studies which are starting to cover the full AGN luminosity range. Preliminary results and time ...
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...

Reverberation mapping methods have been used to measure masses in about three dozen AGNs. The consistency of the virial masses computed from line widths and time delays, the relationship between black hole mass and host-galaxy stellar bulge velocity dispersion, and the consistency with black hole masses estimated from stellar dynamics in the two cases in which such determinations are possible a...
