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)…
From star clusters to dwarf galaxies: The properties of dynamically hot stellar systems
J. Dabringhausen, M. Hilker, P. Kroupa
(Abridged) Objects with radii of 10 to 100 pc and masses in the range from 10^6 to 10^8 M_sun have been discovered during the past decade. These so-called ultra compact dwarf galax…
Stroemgren metallicity calibration: the m1, b-y relation
A. Calamida, G. Bono, P. B. Stetson +15
We performed a new calibration of the Stroemgren metallicity index m1 based on the b-y color of cluster red giant stars. The current Metallicity-Index-Color relation is not linear…
The Outer Cluster System of NGC 1399: Preliminary Results
Y. Schuberth, T. Richtler, B. Dirsch +2
We present preliminary results of our dynamical study of the outer globular cluster system of NGC 1399, the central galaxy in the Fornax Cluster. About 160 new radial velocities fo…
Kinematics in Hickson Compact Group 90
Leonardo Castaneda, Michael Hilker
Using long-slit spectra observed at the VLT (ESO, Paranal) in May 2002, we studied the stellar kinematics in the core of the Hickson Compact Group 90. The line of sight velocity di…
The properties of ultra-compact dwarf galaxies and their possible origin
Michael Hilker, Steffen Mieske
In this contribution the discovery and properties of ultra-compact dwarf galaxies are presented, and their possible origin is discussed. This new type of galaxy resides in the core…
