Investigating Properties of AGNs Through Multi-wavelength Reverberation Mapping

The AGN STORM Collaboration carried out a large, multi-wavelength reverberation-mapping program of NGC 5548, the goals of which are (1) to determine the geometry and kinematics of the broad emission-line region and (2) to measure the central black hole mass. This is the largest UV reverberation program that has ever been undertaken, and it has been supported by optical ground-based imaging and spectroscopy and by space-based observations with Swift, Chandra, andSpitzer. The UV continuum and broad emission lines varied strongly during the course of this campaign, and individual 'events' were well-resolved in time. I will present our results to date from this program.
