Abstract:
We present a study of the globular cluster (GC) systems of four
early-type poststarburst galaxies using deep g- and I-band images from
the Advanced Camera for Surveys aboard the Hubble Space Telescope. All
the galaxies feature shells distributed around their main bodies and
are thus likely merger remnants. The color distribution of the GCs in
all four galaxies shows a broad peak centered on g-I∼1.4, while PGC
6240 and PGC 42871 show a significant number of GCs with g-I∼1.0.
Description:
The four galaxies were observed as part of Hubble Space Telescope
(HST) General Observer program 10227 (PI: Goudfrooij), using the Wide
Field Channel (WFC) of the Advanced Camera for Surveys (ACS) with the
filters F475W and F814W. The observations consisted of several long
exposures plus a few short ones to guarantee getting an unsaturated
galaxy center. The total exposure times were 7874s, 9350s, 8369s,
and 21440s in F475W, and 2712s, 3970s, 5908s, and 7300s in F814W
for PGC 6510, PGC 10922, PGC 42871, and PGC 6240, respectively.
