Photometric observations of Grid Giant Star Survey candidates
D. Bizyaev, V. V. Smith, J. Arenas +1
We compare variability of radial velocity (RV) and brightness for a sample of red giants which were selected as candidates for the Grid Giant Star Survey (GGSS). The purpose of the…
A Comparative Study of Globular Cluster Systems in UGC 9799 and NGC 1129
Myung Gyoon Lee, Eunhyeuk Kim, Doug Geisler +2
We present a preliminary analysis of HST-WFPC2 observations of globular cluster systems in the two brightest galaxies, UGC 9799 (cD) and NGC 1129 (non-cD), located in the center of…
New CCD Survey of Globular Clusters in M31
Myung Gyoon Lee, Sang Chul Kim, Doug Geisler +3
We present a progress report of our wide field CCD survey of globular clusters in M31. We have covered 3 deg X 3 deg area centered on M31, using the KPNO 0.9m and Washington CMT1 f…
Surface Photometry of Star Clusters in the Dwarf Elliptical Galaxies NGC 185 and NGC 205
Sang Chul Kim, Myung Gyoon Lee, Doug Geisler +3
We present the surface photometry of star clusters in the nearby dwarf elliptical galaxies NGC 185 and NGC 205, obtained from deep HST WFPC2 F555W (V) and F814W (I) images. We have…
Washington Photometry of New Globular Clusters in M31
Sang Chul Kim, Myung Gyoon Lee, Doug Geisler +3
We present a progress report on Washington photometry of several hundred new globular cluster (GC) candidates in M31 which were recently found from our new CCD survey of GCs. Washi…
The Outer Halo Cluster System of NGC 1399
B. Dirsch, D. Geisler, T. Richtler +1
We investigate the outer halo globular cluster population of NGC 1399. This study uses wide-field imaging of this cluster system, which covers the largest area studied with CCD pho…
