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 ...
The evidence for jet-cloud interactions in a sample of high/intermediate-redshift radio galaxies
(Blackwell Publishing: Monthly Notices of the Royal Astronomical Society, 2001-05)
We present detailed long-slit spectroscopic observations of a sample of four powerful
radio galaxies, with intermediate/high redshifts (0.47 < z < 0.81). The observations cover the rest-wavelength range 2600 °A- 6600 °A, ...
Testing the photoionization models of powerful radio galaxies: Mixed line-emitting media in 3C 321
(Blackwell Publishing: Monthly Notices of the Royal Astronomical Society, 2000-10)
The photoionization models for the narrow emission line regions of powerful radio galaxies have yet to be tested in depth. To this end, we present high-quality long-slit spectroscopy of the powerful double-nucleus radio ...
