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 ...
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 ...
The nature of the optical: Radio correlations for powerful radio galaxies
(Blackwell Publishing: Monthly Notices of the Royal Astronomical Society, 1998-08)
The nature of the optical–radio correlations for powerful radio galaxies is investigated using spectroscopic observations of a complete sample of southern 2Jy radio sources. In line with previous work, we find that significant ...
