Scientific paper

We present an automated method to detect populations of groups in galaxy redshift catalogs. This method uses both analysis of the redshift distribution along lines of sight in fixed cells to detect elementary structures and a friend-of-friend algorithm to merge these elementary structures into physical structures. We apply this method to the SSRS2 galaxy redshift catalog (Southern Sky Redshift Survey, Da Costa et al., Cat. J/AJ/116/1). The groups detected with our method are similar to group catalogs detected with pure friend-of-friend algorithms. (1 data file).
