The blue Tully-Fisher relation in a variety of environments
Abstract
Expanding previous relevant statistics, the blue absolute luminosities and the corrected 21 cm line widths of about 460 disk galaxies belonging to galaxy groups and to several clusters (Virgo, Pegasus I, A262, A1367, A1656, Zwicky 74-23) have been examined in order to investigate possible environmental dependences of the form of the blue Tully-Fisher relation. Within the limits of the present data, no firm evidence of appreciable environmental effects is found; some implications of this result are briefly discussed.
