HST STIS spectroscopy of the triple nucleus of M31: two nested disks in Keplerian rotation around a Supermassive Black Hole
Ralf Bender, John Kormendy, Gary Bower +12
We present HST spectroscopy of the nucleus of M31 obtained with STIS. Spectra taken around the CaT lines at 8500 see only the red giants in the double bright- ness peaks P1 and P2.…
Mapping the Kinematics of the Narrow-Line Region in the Seyfert Galaxy NGC 4151
V. Das, D. M. Crenshaw, J. B. Hutchings +6
Using The Hubble Space Telescope's Space Telescope Imaging Spectrograph HST's STIS, observations of the OIII emission from the narrow-line region (NLR) of NGC 4151 were obtained an…
Probing the Kinematics of the Narrow-Line Region in Seyfert Galaxies with Slitless Spectroscopy: Observational Results
J. R. Ruiz, D. M. Crenshaw, S. B. Kraemer +5
We present slitless spectra of 10 Seyfert galaxies observed with the Space Telescope Imaging Spectrograph on the Hubble Space Telescope. The spectra cover the [OIII] 4959, 5007 emi…
The Relationship Between Black Hole Mass and Velocity Dispersion in Seyfert 1 Galaxies
Charles H. Nelson, Richard F. Green, Gary Bower +2
Black hole masses in active galactic nuclei (AGN) are difficult to measure using conventional dynamical methods, but can be determined using the technique of reverberation mapping.…
