Next: Other Galaxies with HI Up: Galaxies with Broad HI Previous: NGC 7582 . Table 4 lists a few strongly interacting or merging galaxies which also show broad H I absorption lines. ... Table: Strongly interacting pairs of spirals . ... But in these galaxies the cold gas which feeds the starburst is driven inwards by strong tidal interaction or merging between galaxies (see e.g., Rieke et al. 1985), whereas in the nearby galaxies, bars and/or weak galaxy interactions may be responsible. ...
