Abstract
We have previously demonstrated that Tully-Fisher (TF) residuals correlate with tracers of star formation history (color and emission line equivalent width, EW) for a broad sample of Sa-Sd spiral galaxies (Kannappan, Fabricant, & Franx 2002, KFF). Here we use these correlations to study two other classes of galaxies: (1) galaxies in close pairs, and (2) galaxies at intermediate redshift.
