Abstract:
We investigate the old globular cluster (GC) population of 68 faint
(MV>−16mag) dwarf galaxies located in the halo regions of nearby
(≲12Mpc) loose galaxy groups and in the field environment based on
archival Hubble Space Telescope (HST)/Advanced Camera for Surveys
(ACS) images in F606W and F814W filters.
Description:
The current study is based on HST/ACS archival data from programs
SNAP-9771 and GO-10235, conducted in HST cycles 12 and 13,
respectively (PI: I. Karachentsev), and archival HST/ACS data
(GO-10210, PI: B. Tully) that were described in Georgiev et al.
(2008AJ....135.1858G 2008AJ....135.1858G).
