HI in the Small Magellanic Cloud re-examined.
Abstract
Results of a reexamintation of the neutral hydrogen gas in the Small Magellanic Cloud (SMC), based on observations made with 21 cm receivers are presented. It is found that the shape of Hindman's (1967) contours corresponds well with new data. Ninety-seven percent of the 506 observed profiles had two, three, or four peaks and there are four large masses of H I gas in the SMC which are well separated in radial velocity. Good correlations are found between the radial velocities of H II regions, supergiant stars, and H I, which seem to support the four-velocity assertion. Finally, it is believed that a large trailing halo of H I gas, which forms the major component of the inter-cloud bridge region, is associated with the SMC.
