6. Abstract

We propose to search the HST WFPC2 archive for galaxies whose redshifts are likely
to be in the range 0.2 ~lt z ~lt 1.0 in order to define a complete sample for
spectroscopy using the Hobby-Eberly Telescope (HET). Spectroscopy will be used to
measure the internal kinematics of these galaxies. These data will be combined with
the HST surface-photometry to study the evolution of galaxy mass-to-light ratios
(M/L) by the changes with redshift of the Tully-Fisher relation for spirals. An
independent assessment of evolution will be made via the Tolman surface-brightness
test. HST images are critical for target selection and quantitative measurement of
inclination, position angle, surface-brightness, and galaxy type. The spectroscopic
program represents a major research effort with the HET starting in the coming year;
we anticipate allocating ~150 hours per year of HET time to this project. In this
proposal we request support for the sample selection and definition from archive
data alone.
