The distribution of atomic gas and dust in nearby galaxies - I. Presentation of matched-resolution VLA H I and SCUBA 850-μm maps
We present matched-resolution VLA HI and SCUBA 850-μm maps of 20 IRAS-bright galaxies. Of the galaxies observed, two were not detected in HI and two were detected in absorption. The HI distributions of the galaxies have a range of morphologies. Some of the systems appear HI deficient in the central regions which could be due to a high conversion rate of HI into molecules or HI absorption. In contrast to the HI, the 850-μm emission has a smooth distribution which is concentrated towards the optical centre of each galaxy. We also find evidence for 850-μm emission extending to the periphery of the optical disc in some of the galaxies. Finally, we note that the relative lack of 850-μm emission when compared with HI does not necessarily mean that the atomic gas and dust do not have similar mass distributions.
