Dynamical evidence for environmental evolution of intermediate-redshift spiral galaxies. Moran S.M., Miller N., Treu T., Ellis R.S., Smith G.P. <Astrophys. J., 659, 1138-1152 (2007)> =2007ApJ...659.1138M

By modeling the observed rotation curves, we derive maximal rotation velocities for 40 cluster spirals and 37 field spirals, yielding one of the largest matched samples of cluster and field spirals at intermediate redshift. We construct the Tully-Fisher (TF) relation in both V and Ks bands, and find that the cluster Tully-Fisher relation exhibits significantly higher scatter than the field relation, in both V and Ks bands. Description: We make use of HST imaging of Cl 0024 (ClG 0024+1652) and MS 0451 (ClG 0451-03) from the comprehensive wide-field survey described in Treu et al. (2003, Cat. J/ApJ/591/53) and G.P. Smith et al. (2007, in preparation). We also use panoramic ground-based Ks-band imaging of both clusters, and J-band imaging of Cl 0024, with the WIRC camera on the Hale 200 inch (5.08m) Telescope. Observations were made in 2004 November for MS 0451 and 2002 October for Cl 0024. The details of the observations and data reduction are described by Smith et al. (2005ApJ...620...78S) and G.P. Smith et al. (2007, in preparation) for Cl 0024 and MS 0451, respectively. File Summary:

Note (1): Typical formal errors on Rs, i, and SlPA are 10%, 0.5° and 1°, respectively, and systematic uncertainties in i and SlPA are typically ∼10°. Note (2): corrected for inclination-dependent internal extinction. Note (3): Rotation curve quality as follows: 1 = curves display turnovers on both ends 2 = curves display only one turnover, or an uncertain fit
