Abstract:
We study the photometric and structural properties of
spectroscopically confirmed members in the two massive X-ray-selected
z∼0.83 galaxy clusters MS 105403 and RX J0152.7-1357 using three-band
mosaic imaging with the Hubble Space Telescope Advanced Camera for
Surveys. The samples include 105 and 140 members of RX J0152.7-1357
and MS 105403, respectively, to i775<24.0. A quantitative
classification scheme using Sersic indices and "bumpiness" (the ratio
of the rms residuals to the model mean) was found to correlate well
with visual morphological type. The color-magnitude residuals
correlate well with the local density, as measured from both galaxy
numbers and weak lensing. Weaker correlations are found with cluster
radius (the fundamental dependence is on local density).
Description:
The clusters RX J0152.7-1357 and MS 1054-03 were observed with the
ACS WFC using a 2x2 overlapping mosaic pattern. The usable area of
each mosaic was about 5.8' on a side. RX J0152.7-1357 was observed
in 2002 November in the F625W, F775W, and F850LP bandpasses for two
orbits apiece at each of the four mosaic positions. MS 1054-03 was
observed in 2002 December in the F775W and F850LP bandpasses for two
orbits apiece, and in 2004 January/February in the F606W bandpass for
one orbit, at each mosaic position.
