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 large scale distribution of warm ionized gas around nearby radio galaxies with jet-cloud interactions
(Blackwell Publishing: Monthly Notices of the Royal Astronomical Society, 2000-06)
Deep, narrow-band Halpha observations taken with the TAURUS Tunable Filter (TTF) on the 4.2m WHT telescope are presented for two nearby radio galaxies with strong jet-cloud interactions. Although the brightest emission ...
