Circumnuclear HI disks in radio galaxies: The case of Cen A and B2 0258+35
Christian Struve, Raffaella Morganti, Tom A. Oosterloo
New HI observations of the nearby radio-loud galaxies Centaurus A and B2 0258+35 show broad absorption (Delta_v=400km/s) against the unresolved nuclei. Both sources belong to the c…

Centaurus A: Morphology and kinematics of the HI disk
Christian Struve, Raffaella Morganti, Tom A. Oosterloo
We present first results of new ATCA HI emission and absorption observations of Centaurus A. The large-scale disk is described via a tilted-ring model. A broader redshifted absorpt…
