Large Gas Disks in Radiogalaxies
R. Morganti, T. A. Oosterloo, S. Tinti +3
Large-scale (up to 100 kpc) HI structures have been found in three radio galaxies using the WSRT and the VLA. In one case, the HI has been detected in emission while in the other t…
Shocks, illumination cones and intrinsic gas structures in the extreme radio galaxy 3C265
C. Solorzano-Inarrea, C. Tadhunter, J. Bland-Hawthorn
We present deep, narrow-band and continuum images of the powerful z=0.811 radio galaxy 3C265, taken with the TTF on the WHT, together with detailed long-slit spectroscopic observat…
High-Resolution Mid-Infrared Morphology of Cygnus A
James T. Radomski, Robert K. Pina, Christopher Packham +2
We present subarcsecond resolution mid-infrared images at 10.8 and 18.2 microns of Cygnus A. These images were obtained with the University of Florida mid-IR camera/spectrometer OS…
HI absorption from the central kpc of radio galaxies: effect of orientation or interstellar medium?
R. Morganti, T. A. Oosterloo, C. N. Tadhunter +6
We present a summary of recent studies of HI absorption in radio galaxies. The results show how the absorption can be due to a variety of phenomena and how they can help us in unde…
Emission line outflows in PKS1549-79: the effects of the early stages of radio source evolution?
C. Tadhunter, K. Wills, R. Morganti +2
We present new spectroscopic observations of the southern radio galaxy PKS1549-79 (z =0.152).Despite the flat spectrum character of the radio emission from this source, our optical…
