Fast neutral outflows in powerful radio galaxies: a major source of feedback in massive galaxies
R. Morganti, C. N. Tadhunter, T. A. Oosterloo
We report the detection of fast (~ 1000 km/s), massive outflows of neutral gas observed -- using the WSRT -- as 21-cm HI absorption against the strong radio continuum of seven radi…
Gas and dust properties in the afterglow spectra of GRB 050730
R. L. C. Starling, P. M. Vreeswijk, S. L. Ellison +9
We present early WHT ISIS optical spectroscopy of the afterglow of gamma-ray burst GRB 050730. The spectrum shows a DLA system with the highest measured hydrogen column to date: N(…
Outflows and shocks in compact radio sources
J. Holt, C. N. Tadhunter, R. Morganti
We report some key results from the optical emission line study of a complete sample of compact radio sources. We find strong evidence for jet-driven outflows in the circum-nuclear…
Merger-origin of radio galaxies investigated with H I observations
B. H. C. Emonts, R. Morganti, T. A. Oosterloo +4
We present results of an HI study of a complete sample of nearby radio galaxies. Our goal is to investigate whether merger or interaction events could be at the origin of the radio…
Resolving the Shocks in Radio Galaxy Nebulae: HST and Radio Imaging of 3C 171, 3C277.3 and PKS2250-41
Avanti Tilak, Christopher P. O'Dea, Clive Tadhunter +5
We present the results of HST/WFPC2 medium and narrow band imaging and VLA and MERLIN2 radio imaging of three powerful radio galaxies: 3C 171, 3C 277.3, and PKS 2250-41. We obtaine…
A jet-induced outflow of warm gas in 3C 293
B. H. C. Emonts, R. Morganti, C. N. Tadhunter +3
Using long slit emission-line spectra we detect a fast outflow of ionized gas, with velocities up to 1000 km/s, in the nearby powerful radio galaxy 3C 293 (z = 0.045). The fast out…
