Abstract (from CDS):

We present new observations leading to an improved black hole mass estimate for the Seyfert 1 galaxy NGC 4593 as part of a reverberation-mapping campaign conducted at the MDM Observatory. Cross-correlation analysis of the Hβ emission-line light curve with the optical continuum light curve reveals an emission-line time delay of τcent=3.73±0.75 days. By combining this time delay with the Hβ line width, we derive a central black hole mass of MBH=(9.8±2.1)x106 M☉, an improvement in precision of a factor of several over past results.
