Dynamical versus Stellar Masses of Ultracompact Dwarf Galaxies in the Fornax Cluster
Igor Chilingarian, Steffen Mieske, Michael Hilker +1
The origin of ultracompact dwarf (UCD) galaxies, compact extragalactic stellar systems, is still a puzzle for present galaxy formation models. We present the comprehensive analysis…
Formation Efficiencies of Old Globular Clusters - from Dwarf to Giant Galaxies
I. Y. Georgiev, T. H. Puzia, P. Goudfrooij +1
For the full galaxy mass range, we find that previously observed trends of globular cluster (GC) system scaling parameters (number, luminosity or mass of all GCs in a galaxy normal…
Direct N-body simulations of globular clusters: (I) Palomar 14
Akram Hasani Zonoozi, Andreas H. W. Kuepper, Holger Baumgardt +3
We present the first ever direct -body computations of an old Milky Way globular cluster over its entire life time on a star-by-star basis. Using recent GPU hardware at Bonn Uni…
Two formation channels of UCDs in Hickson Compact Groups
C. Da Rocha, S. Mieske, I. Y. Georgiev +3
The formation of ultra-compact dwarf galaxies (UCDs) is believed to be interaction driven, and UCDs are abundant in the cores of galaxy clusters, environments that mark the end-poi…
Globular Cluster Systems in Nearby Dwarf Galaxies: III. Formation Efficiencies of Old Globular Clusters
Iskren Y. Georgiev, Thomas H. Puzia, Paul Goudfrooij +1
We investigate the globular cluster (GC) system scaling parameters as a function of galaxy mass, i.e. specific frequency (S_N), specific luminosity (S_L), specific mass (S_M), and…
Chemodynamics of Compact Stellar Systems in NGC 5128: How similar are Globular Clusters, Ultra-Compact Dwarfs, and Dwarf Galaxies?
Matthew A. Taylor, Thomas H. Puzia, Gretchen L. Harris +3
Velocity dispersion measurements are presented for luminous GCs in NGC 5128 derived from high-res. UVES spectra. The measurements are made with the pPXF code that parametrically re…
