HI absorption from the central kpc of radio galaxies: effect of orientation or interstellar medium?
R. Morganti, T. A. Oosterloo, C. N. Tadhunter +6
We present a summary of recent studies of HI absorption in radio galaxies. The results show how the absorption can be due to a variety of phenomena and how they can help us in unde…

The vertical structure and kinematics of HI in spiral galaxies
Renzo Sancisi, Filippo Fraternali, Tom Oosterloo +1
We discuss the distribution and kinematics of neutral hydrogen in the halos of spiral galaxies. We focus in particular on new results obtained for the nearby Sc galaxy NGC 2403 whi…

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…
