The jet and circumnuclear environment of 3C 293
(Astrophysical Journal, 2006-03-01)
We present the new HST near-infrared polarimetry, broad and narrow-band imaging,
and MERLIN 4.5GHz Multi-Frequency Synthesis radio imaging of 3C 293, a unique radio galaxy whose host is an obvious merger remnant, in an ...
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 ...
Observations of the neutral gas and dust in the radio galaxy 3C305
(Blackwell Publishing: Monthly Notices of the Royal Astronomical Society, 2003-01)
We present MERLIN and Hubble Space Telescope (HST) observations of the central region of the nearby radio galaxy 3C305 and use them to study the gas and dust in this object. TheMERLIN observations are of neutral hydrogen ...
Highly polarized structures in the near-nuclear regions of Cygnus A: Intrinsic anisotropy within the cones?
(Blackwell Publishing: Monthly Notices of the Royal Astronomical Society, 2000-04)
We present near-IR imaging polarimetry observations of the nucleus of Cygnus A, taken with the NICMOS camera of the HST at a wavelength of 2.0µm. These maps reveal a highly collimated region of polarized emission straddling ...
