HIGH-VELOCITY CLOUDS IN THE NEARBY SPIRAL GALAXY M 83

HIGH-VELOCITY CLOUDS IN THE NEARBY SPIRAL GALAXY M 83

We present deep H I 21 cm and optical observations of the face-on spiral galaxy M 83 obtained as part of a project to search for high-velocity clouds (HVCs) in nearby galaxies. Anomalous-velocity neutral gas is detected toward M 83, with 5.6 × 107 M ☉ of H I contained in a disk rotating 40-50 km s-1...
