An Intrinsic Baldwin Effect in the H-beta Broad Emission Line in the Spectrum of NGC 5548
Karoline M. Gilbert, Bradley M. Peterson
We investigate the possibility of an intrinsic Baldwin Effect (i.e.,nonlinear emission-line response to continuum variations) in the broad H-beta emission line of the active galaxy…
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…
Masses of Black Holes in Active Galactic Nuclei
Bradley M. Peterson
We present a progress report on a project whose goal is to improve both the precision and accuracy of everberation-based black-hole masses. Reverberation masses appear to be accura…
The Structure and Energetics of Active Galactic Nuclei
Bradley M. Peterson
The black-hole/accretion-disk paradigm for active galactic nuclei (AGNs) is now reasonably secure, but there are still important unresolved issues, some of which will require the c…
Observational Requirements for High-Fidelity Reverberation Mapping
Keith Horne, Bradley M. Peterson, Stefan J. Collier +1
We present a series of simulations to demonstrate that high-fidelity velocity-delay maps of the emission-line regions in active galactic nuclei can be obtained from time-resolved s…
