Scientific paper

We present a moderate resolution H I map of the amorphous galaxy NGC 4670. Our previous lower resolution data had shown a symmetric H I distribution centered on the single supergiant H II region and highly concentrated to the center of the galaxy. We now resolve the central H I distribution into three clouds, with the eastern cloud located on the central H II region and 1.1 kpc from the westernmost cloud. Masses of the clouds are of order 108 Msun and are associated with the intense central star formation that has produced a luminous, compact star cluster. The central gas surface density is very high at the new resolution, and the surface density drops off rapidly with radius. We determine a rotation curve for the galaxy; however, the low and uncertain value of the inclination (i ˜28°) and the possible presence of a warp make the derived rotation speed (VR ˜110 km s-1) quite uncertain. There is some correspondence between features in the H I distribution and locations of Hα loops and filaments that emanate from the central H II region.
