The Advanced Camera
for Surveys is a new powerful camera that was fitted to the Hubble Space
Telescope in March 2002. We (Franx and Miley) are members of the ACS Science
Team (AST). In recognition for their contribution in developing the ACS, NASA
awarded the ACT about 650 orbits of observing time on Hubble. These data are
being taken during the period 2002 - 2005.
The major scientific
goal of the AST in using their guaranteed time (~300 orbits) is to use the
superior sensitivity, wide field and angular resolution of the ACS to study
clusters of galaxies over a huge range of distance, ranging from the nearby
Universe to the most distant galaxy structures known.
The ACS data (unique
spatial resolution) will be compared with ground-based data from large telescopes,
such as the VLT (kinematics and colors). The aims will be to use the new ACS
data to constrain the formation and evolution of galaxy clusters. Specific
goals of the proposed workshop will be (i) to present and discuss the first
data and (ii) to write drafts of relevant papers. A Lorentz-style workshop
format is ideal for achieving these goals.
