The warped nuclear disk of radio galaxy 3C 449
(Astrophysical Journal, 2006)
Among radio galaxies containing nuclear dust disks, the bipolar jet axis is generally observed to be perpendicular to the disk major axis. The FR I radio source 3C 449 is an outlier to this statistical
majority, as it ...
Supermassive black hole mass measurements for NGC 1300 and NGC 2748 based on HST [Hubble Space Telescope] emission-line gas kinematics
(Blackwell Publishing: Monthly Notices of the Royal Astronomical Society, 2005-05)
We present Space Telescope Imaging Spectrograph emission-line spectra of the central regions of the spiral galaxies NGC 1300 and NGC 2748. From the derived kinematics of the nuclear gas we have found evidence for central ...
The supermassive black hole in the Seyfert 2 galaxy NGC 5252
(EDP Sciences: Astronomy & Astrophysics, 2005-02)
We present results from HST/STIS long-slit spectroscopy of the gas motions in the nuclear region of the Seyfert 2 galaxy NGC 5252. The observed velocity field is consistent with gas in regular rotation with superposed ...
The Narrow Line Region of NGC 4151: A Turbulent cauldron
(University of Chicago Press: Astrophysical Journal Letters, 1997-10-01)
We present the first results of the Hubble Space Telescope/Faint Object Camera long-slit spectroscopy of the inner 8′′ of the Narrow Line Region of NGC4151 at a spatial resolution of 0′′.029. The emission gas is characterized ...
Jet driven motions in the Narrow Line region of NGC1068
(Springer Netherlands: Astrophysics and Space Science, 1997-03)
We have obtained HST FOC f/48 long-slit spectroscopy of the inner 4" of the Narrow Line Region of NGC 1068 between 3500-5400A with a spectral resolution of 1.78A/pixel. At a spatial scale of 0.0287" per pixel these data ...
