HI gas disks in elliptical galaxies
E. M. Sadler, T. Oosterloo, R. Morganti
We discuss a class of low-luminosity E/S0 galaxies which have both HI disks and (in contrast to more luminous E/S0s with HI) ongoing star formation. We suggest that such objects ar…
HI absorption in radio galaxies: effect of orientation or interstellar medium?
R. Morganti, T. A. Oosterloo, C. N. Tadhunter +3
A search for HI absorption has been made in 23 radio galaxies using the ATCA, the VLA and the WSRT. In five galaxies HI absorption was detected. We investigate how the detection ra…
HI absorption and the ISM around radio galaxies
R. Morganti, T. A. Oosterloo, C. N. Tadhunter +3
We present a study, done with the Australian LBA, of HI absorption for two compact radio galaxies (PKS 1549-79 and PKS 1814-63). In both the radio galaxies, the HI appears to give…
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 in Early-Type Galaxies
T. Oosterloo, R. Morganti, E. M. Sadler
We briefly discuss the main differences between the HI properties of luminous and low-luminosity early-type galaxies. In luminous early-type galaxies the HI is often irregularly di…
Neutral and ionized gas distribution in and around the radio galaxy Coma A
R. Morganti, T. Oosterloo, C. N. Tadhunter +1
HI absorption has been detected with the WSRT against both lobes of the radio galaxy Coma A. This radio galaxy could be expanding in a particularly gas rich environment, perhaps th…
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…
An Extragalactic HI Cloud with No Optical Counterpart?
V. A. Kilborn, L. Staveley-Smith, M. Marquarding +25
We report the discovery, from the HI Parkes All-Sky Survey (HIPASS), of an isolated cloud of neutral hydrogen which we believe to be extragalactic. The HI mass of the cloud (HIPASS…
A strong jet/cloud interaction in the Seyfert galaxy IC 5063: VLBI observations
T. A. Oosterloo, R. Morganti, A. Tzioumis +4
We present 21-cm HI line and 13-cm continuum observations, obtained with the Australian Long Baseline Array, of the Seyfert 2 galaxy IC 5063. This object appears to be one of the b…
