| Abstract | We present HI synthesis and optical CCD data for pairs of spiral galaxies chosen in an objective manner from the CfA redshift catalog. This is a simple extension to higher velocity differences and higher background galaxy density (i.e. to densities comparable to that of loose groups, called `medium' density here) of an earlier study on field galaxy pairs (Chengalur, Salpeter & Terzian 1994). The extension to higher b ... |
