Abstract. Here we present preliminary results of a study of the neutral hydrogen gas (HI) in the southern spiral galaxies NGC 7582, NGC 7590, and NGC 7599 with the Australia Telescope Compact Array .
Keywords. Galaxies: individual (NGC 7582, NGC 7590, NGC7599) - starburst - tidal interaction - kinematics and dynamics.
Figure 1: HI distribution of the interacting galaxy group consisting of
NGC 7582 (right), NGC 7599 (left) and NGC 7590 (middle). Tidal tails are
clearly visible to the north and west of NGC 7582.
(The colour gradient is in units of Jansky/beam km/s.)
Figure 2: HI mean velocity field of the same group.
(The colour gradient is in units of km/s.)
Figure 3: HI mean velocity dispersion of the same group.
(The colour gradient is in units of km/s.)
An overlay of the HI distribution and optical emission (Figure 4) is available here (222 kbyte).
