Globular cluster systems in nearby dwarf galaxies - II. Nuclear star clusters and their relation to massive Galactic globular clusters (2009)

Georgiev, Iskren Y., Hilker, Michael, Puzia, Thomas H., Goudfrooij, Paul, Baumgardt, Holger

(Abridged) Using luminosities and structural parameters of globular clusters (GCs) in the nuclear regions (nGCs) of low-mass dwarf galaxies from HST/ACS imaging we derive the present-day escape...

Globular Cluster Systems in Nearby Dwarf Galaxies: I. HST/ACS Observations and Dynamical Properties of Globular Clusters at Low Environmental Density (2008)

Georgiev, Iskren Y., Puzia, Thomas H., Hilker, Michael, Goudfrooij, Paul

We investigate the old globular cluster (GC) population of 68 faint (Mv>-16 mag) dwarf galaxies located in the halo regions of nearby (

Old globular clusters in magellanic-type dwarf irregular galaxies (2008)

Georgiev, Iskren Y., Goudfrooij, Paul, Puzia, Thomas H., Hilker, Michael

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) associations of...

Georgiev, Iskren Y., Hilker, Michael, Puzia, Thomas H., Chaname, Julio, Mieske, Steffen, Goudfrooij, Paul, ...

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 bands under...
