Globular Cluster Systems in Nearby Dwarf Galaxies: I. HST/ACS Observations and Dynamical Properties of Globular Clusters at Low Environmental Density
Iskren Y. Georgiev, Thomas H. Puzia, Michael Hilker +1
We investigate the old globular cluster (GC) population of 68 faint (Mv>-16 mag) dwarf galaxies located in the halo regions of nearby (<12 Mpc) loose galaxy groups and in the field…
Old globular clusters in magellanic-type dwarf irregular galaxies
Iskren Y. Georgiev, Paul Goudfrooij, Thomas H. Puzia +1
We present a study of the old globular clusters (GC) using archival F606W and F814W HST/ACS images of 19 Magellanic-type dwarf Irregular (dIrr) galaxies found in nearby (2 - 8 Mpc)…
The old globular cluster system of the dIrr galaxy NGC1427A in the Fornax cluster
Iskren Y. Georgiev, Michael Hilker, Thomas H. Puzia +5
We present a study of the old globular cluster (GC) population of the dwarf irregular galaxy NGC 1427A using multi-wavelength VLT observations in U, B, V, I, H_alpha, J, H, and Ks…
