In order to improve the reverberation-mapping-based estimate of the mass of the central supermassive black hole in the Seyfert 1 galaxy NGC 4151, we have reanalyzed archival ultraviolet monitoring spectra from two campaigns undertaken with the International Ultraviolet Explorer. We measure emission-line time delays for four lines, C IV λ1549, He II λ1640, C III] λ1909, and Mg II λ2798, from both campaigns. We combine these measurements with the dispersion of the variable part of each respective… Expand
A REVERBERATION-BASED MASS FOR THE CENTRAL BLACK HOLE IN NGC 4151
We have undertaken a new ground-based monitoring campaign to improve the estimates of the mass of the central black hole in NGC 4151. We measure the lag time of the broad H? line response compared toExpand
