Poster Title: SMBH Mass derived from 2D-Reverberation and Gravitational Redshift Measurements
Abstract: Reverberation mapping of variable line intensities in AGN gives us information on the size of the broad line emitting region. The combination of the size with the internal velocity of the line emitting region (line width) allows us to estimate the central black hole mass in AGN.
The 2D-Reverberation mapping method of the variable line profiles yields the geometry and velocity gradient in the BLR more accurately. We present results of a spectral variability campaign of Mrk110 carried out with the 9.2m HET telescope at McDonald Observatory. The additional detection of a gravitational redshift effect in the optical emission line profiles gives us an independently derived value of the central black hole mass. The mutual comparison of these two black hole mass estimates allows us to derive the inclination angle of the central disk and therefore of the spin orientation of the black hole.
