HI absorption and the ISM around radio galaxies
R. Morganti, T. A. Oosterloo, C. N. Tadhunter +3
We present a study, done with the Australian LBA, of HI absorption for two compact radio galaxies (PKS 1549-79 and PKS 1814-63). In both the radio galaxies, the HI appears to give…
Neutral and ionized gas distribution in and around the radio galaxy Coma A
R. Morganti, T. Oosterloo, C. N. Tadhunter +1
HI absorption has been detected with the WSRT against both lobes of the radio galaxy Coma A. This radio galaxy could be expanding in a particularly gas rich environment, perhaps th…
HI absorption in radio galaxies
R. Morganti, T. A. Oosterloo, G. van Moorsel +2
Twenty-two powerful radio galaxies have been searched for HI absorption. We find the highest probability of detecting HI in absorption among narrow-line compact (or small) galaxies…
Testing the photoionization models of powerful radio galaxies: Mixed line-emitting media in 3C 321
T. G. Robinson, C. N. Tadhunter, D. J. Axon +1
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 spectrosco…
Highly polarized structures in the near-nuclear regions of Cygnus A: intrinsic anisotropy within the cones?
C. N. Tadhunter, W. Sparks, D. J. Axon +6
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 2.0 microns.These maps reveal a highly co…
The large scale distribution of warm ionized gas around nearby radio galaxies with jet-cloud interactions
C. N. Tadhunter, M. Villar-Martin, R. Morganti +2
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 interac…
