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…
Fast outflow of neutral and ionized gas from the radio galaxy 3C 293
B. H. C. Emonts, R. Morganti, T. A. Oosterloo +2
We detect a fast outflow of neutral and ionized gas with velocities up to about 1000 km/s from the central region of radio galaxy 3C 293. With optical spectroscopy we locate the bu…
The extra-planar neutral gas in the edge-on spiral galaxy NGC 891
Filippo Fraternali, Tom Oosterloo, Renzo Sancisi +1
We present neutral hydrogen observations of the nearby edge-on spiral galaxy NGC891 which show extended extra-planar emission up to distances of 15 kpc from the plane. 3D modeling…
Outflows of neutral (and ionized) gas in radio galaxies
R. Morganti, T. Oosterloo, C. Tadhunter
Outflows up to 1500 km/s of atomic neutral hydrogen are detected in a growing number of radio galaxies. Outflows with similar velocities are also detected in ionized gas, suggestin…
High velocity HI in NGC 6946 and extra-planar gas in NGC 253
Rense Boomsma, Tom Oosterloo, Filippo Fraternali +2
Multi-wavelength observations of nearby spiral galaxies have shown that neutral and ionized gas are present up to a few kpc from the disk and that star formation and supernovae pro…
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.
