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…
Neutral hydrogen in radio galaxies: results from nearby, importance for far away
Raffaella Morganti
The study of neutral hydrogen emission and absorption in radio galaxies is giving new and important insights on a variety of phenomena observed in these objects. Such observations…
The very late-stage merger IC 4200:pre-elliptical or pre-spiral?
P. Serra, S. C. Trager, J. M. van der Hulst +3
Recent observations have revealed a class of unusually HI-rich early-type galaxies. By combining observations of their morphology, stellar populations and neutral hydrogen we aim t…
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…
A dark jet dominates the power output of the stellar black hole Cygnus X-1
E. Gallo, R. Fender, C. Kaiser +4
Accreting black holes are thought to emit the bulk of their power in the X-ray band by releasing the gravitational potential energy of the infalling matter. At the same time, they…
