Centaurus A: Morphology and kinematics of the HI disk
arXiv:0712.1900
Abstract
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 absorption than previously known as well as a blueshifted absorption component against the nucleus is found.
