Structure and kinematics of edge-on galaxy discs - II. Observations of the neutral hydrogen
Abstract
We present Australia Telescope Compact Array and Westerbork Synthesis Radio Telescope HI observations of 15 edge-on spiral galaxies of intermediate to late morphological type. The global properties and the distribution and kinematics of the HI gas are analysed and discussed. We determine the rotation curves using the envelope-tracing method. For 10 spiral galaxies with a stellar disc truncation we find an average ratio of the HI radius to the truncation radius of the stellar disc of 1.1 +/- 0.2 (1σ).
