Abstract:
We have measured maximum rotation velocities (Vrot) for a sample of
111 emission-line galaxies with 0.1~<z~<1, observed in the fields of
six clusters. From these data we construct 'matched' samples of 58
field and 22 cluster galaxies, covering similar ranges in redshift
(0.25≤z≤1.0) and luminosity (MB≤-19.5mag), and selected in a
homogeneous manner.
Description:
The photometry used in this study is primarily from the HST archive
and our own FORS2 R-band imaging. These are supplemented with
additional reduced and zero-point calibrated ground-based data, kindly
provided by Dr. Ian Smail, in order to provide colour information.
The multislit spectroscopy for this study was observed using the MXU
mode of FORS2 on the VLT.
