Black Hole Masses in Three Seyfert Galaxies
C. A. Onken, B. M. Peterson, M. Dietrich +2
We analyze published reverberation mapping data for three Seyfert galaxies (NGC 3227, NGC 3516, and NGC 4593) to refine the mass estimate for the supermassive black hole in the cen…
Steps Toward Determination of the Size and Structure of the Broad-Line Region in Active Galactic Nuclei. XVI. A Thirteen-Year Study of Spectral Variability in NGC 5548
B. M. Peterson, the International AGN Watch
We present the final installment of an intensive 13-year study of variations of the optical continuum and broad H-beta emission line in the Seyfert 1 galaxy NGC 5548. The data base…
The Mass of the Central Black Hole in the Seyfert Galaxy NGC 3783
Christopher A. Onken, Bradley M. Peterson
Improved analysis of ultraviolet and optical monitoring data on the Seyfert 1 galaxy NGC 3783 provides evidence for the existence of a supermassive, (8.7+/-1.1)x10^6 M_sun, black h…
