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…
Structure and Evolution of Nearby OB Associations
P. T. de Zeeuw, A. G. A. Brown, J. H. J. de Bruijne +4
We present the first results of a comprehensive census of the stellar content of the nearby OB associations based on Hipparcos positions, proper motions and parallaxes for 12842 ca…
New Results for Three Nearby OB Associations
R. Hoogerwerf, J. H. J. de Bruijne, A. G. A. Brown +3
We have developed a new procedure to identify moving groups, and have applied it to carry out a census of the nearby OB associations based on Hipparcos parallaxes and proper motion…
