Advances in Reverberation Mapping

Reverberation Mapping and Broad-Line Region Models

I review what we have learned about the BLR from reverberation mapping, point to some problems and complications that have emerged, and outline some future directions.

Reverberation mapping is a proven technique that is used to measure the size of the broad emission-line region and central black hole mass in active galactic nuclei. More ambitious reverberation mapping programs that are well within the capabilities of Hubble Space Telescope could allow us to determine the nature and flow of line-emitting gas in active nuclei and to assess accurately the system...

Reverberation Mapping and the Physics of Active Galactic Nuclei

Reverberation-mapping campaigns have revolutionized our understanding of AGN. They have allowed the direct determination of the broad-line region size, enabled mapping of the gas distribution around the central black hole, and are starting to resolve the continuum source structure. This review describes the recent and successful campaigns of the International AGN Watch consortium, outlines the ...

Testing Radiation Pressure Corrections to Reverberation Mapping Masses

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 sufficientl...
