Holes and high velocity HI in NGC 6946
Rense Boomsma, Tom Oosterloo, Thijs van der Hulst +2
We are studying the properties of the holes and the high velocity gas in NGC 6946. Here we present some puzzling results.
High Velocity Gas in the Halos of Spiral Galaxies
Filippo Fraternali, Tom Oosterloo, Rense Boomsma +2
Recent, high sensitivity, HI observations of nearby spiral galaxies show that their thin `cold' disks are surrounded by thick layers (halos) of neutral gas with anomalous kinematic…
Tidal Remnants and Intergalactic HII Regions
T. Oosterloo, R. Morganti, E. M. Sadler +3
We report the discovery of two small intergalactic HII regions in the loose group of galaxies around the field elliptical NGC 1490. The HII regions are located at least 100 kpc fro…
Gas outflows in radio galaxies
R. Morganti, T. Oosterloo, B. H. C. Emonts +2
We present a summary of our recent results on gas outflows in radio galaxies. Fast outflows (up to 2000 km/s) have been detected both in ionized and neutral gas. The latter is part…
HI on large and small scales in starburst radio galaxies
Raffaella Morganti, Tom Oosterloo, Clive Tadhunter +2
The study of the optical continuum of radio galaxies shows that about 30% have a young stellar population component. Among them are the most far-IR bright radio galaxies. A further…
