This a revised phaseII using WFPC2 on two fields in one galaxy cluster. I have chosen field centers and orienations to maximize overlap with our spectroscopic sample, but also such that the visits should be schedulable in late May early June. Other orientations are possible, with small changes in the target coordinates. Please contact me asap if the current orientations pose a problem for the schedule. Thanks. - Inger ----- Submission 1 (Mon May 15 23:37:08 GMT 2006) ----- ----- Submission 2 (Sat Mar 10 01:45:56 GMT 2007) ----- Assigned ID: 324 ----- Submission 1 (Fri Jan 27 18:46:13 GMT 2006) ----- Galaxy Evolution During Half the Age of the Universe: ACS imaging of rich galaxy clusters 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.
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.
