Abstract

Detailed studies of nearby galaxies (z<0.05) show that galaxies have very complex
histories of formation and evolution involving mergers, bursts of star formation,
and morphological changes. Even so, the global properties of the galaxies (radii,
luminosities, rotation velocities, velocity dispersions, and absorption line
strengths) follow a number of very tight (empirical) scaling relations, e.g. the
Tully-Fisher relation and the Fundamental Plane (FP). We use the scaling relations
plus quantative morphological measures for galaxy clusters up to z=1 to constrain
models for galaxy evolution. Here we request 24 orbits to obtain ACS imaging of the
remaining three clusters in our sample at z~0.7-1.0. High resolution imaging of the
clusters is critical for our study of star formation histories and structural
evolution in dense environments since z<1. We have previously obtained deep
spectroscopic observations of the clusters with Gemini. The data will provide
samples large enough to establish the slope of the FP for each cluster. With
multiple clusters at similar redshifts, we can probe evolutionary differences within
a single epoch in order to decouple changes due to different environments. Our two
other high-z clusters exhibit different chemical enrichment histories, which we
argue are due to the different merging histories of these clusters.

  Observations Description
  ------------------------

     This phaseII has been updated to use WFPC2 for a program that originally used
     ACS/WFC. The original program was for three galaxy clusters, 2 fields in each.
     The revised WFPC2 are for two fields in one cluster MS1610.4+6616. The fields
     are placed and oriented such that the overlap with already obtained ground-
     based observations are optimized. All observations are obtained in F702W. Other
     orientations are possible with small changes to the target coordinates. If the
     current orientations pose scheduling difficulties, please contact the PI for
     info on other possible orientations (and the adjusted target coordinates for
     these). For each field, a total of 6 dither points are used. Visits 1-4 are for
     field 1 and are all identical, except for the orientation of visits 2-4 being
     linked to the actual orientation used for visit 1. Multiple visits are only
     used aid scheduling, but they could in principle be executed one right after
     the other. Similarly visits 5-8 are identical and cover the other field. Each
     visit is 3 orbits, for a total of 24 orbits. The orientation of each has been
     optimized to the best overlap with our ground based observations. The
     orientation was determined by interactive use of the VTT using a ground based
     CCD image of the cluster. The CCD image had a WCS consistent with the ICRS
     reference frame.

Visit: 12
     Visit Priority:      <none>
     Visit Requirements:  PCS MODE FINE; ORIENT -5.0D TO 5.0D FROM 11
     On Hold Comments:    <none>
     Additional Comments: The orientation for the observation is optimized to have the best overlap
                          with our ground based observations. If there are scheduling difficulties,
                          different orienations are possible with small adjustments to the target
                          coordinates. Please contact the PI in this case. The target for visit 12 is
                          the same as for visit 11, and we request that visit 12 is taken within +-
                          5deg of the orientation used for visit 11.
