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 ...
Spectroscopy of the near-nuclear regions of Cygnus A: Estimating the mass of the supermassive black hole
(Blackwell Publishing: Monthly Notices of the Royal Astronomical Society, 2003-07)
We use a combination of high spatial resolution optical and near-IR spectroscopic data to make a detailed study of the kinematics of the NLR gas in the near-nuclear regions of the powerful, FRII radio galaxy Cygnus A ...
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 ...
