Kinematic Evolution of Field and Cluster Spiral Galaxies
  We investigate the evolution of the Tully-Fisher relation out to z=1 with 137
emission-line galaxies in the field that display a regular rotation curve. They
follow a linear trend with lookback time being on average brighter by 1.1Bmag
and 60% smaller at z=1. For a subsample of 48 objects with very regular gas
kinematics and stellar structure we derive a TF scatter of 1.15mag, which is
two times larger than local samples exhibit. This is probably due to modest
variations in their star formation history and chemical enrichment. In another
study of 96 members of Abell 901/902 at z=0.17 and 86 field galaxies with
similar redshifts we find a difference in the TFR of 0.42mag in the B-band but
no significant difference in stellar mass. Comparing specifically red spirals
with blue ones in the cluster, the former are fainter on average by 0.35Bmag
and have 15% lower stellar masses. This is probably due to star formation
quenching caused by ram-pressure in the cluster environment. Evidence for this
scenario comes from strong distortions of the gas disk of red spirals that have
at the same time a very regular stellar disk structure.
