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…
Galaxy Disruption Caught in the Act
A. M. Karick, M. J. Drinkwater, M. West +2
Direct evidence of stellar material from galaxy disruption in the intra-cluster medium (ICM) relies on challenging observations of individual stars, planetary nebulae and diffuse o…
Potential of the Surface Brightness Fluctuation method to measure distances to dwarf ellipticals in nearby clusters
S. Mieske, M. Hilker, L. Infante
The potential of the Surface Brightness Fluctuation (SBF) method to determine distances to dwarf ellipticals in nearby clusters is investigated. We find that for the Fornax cluster…
Globular Clusters in the Central Region of Nearby Galaxy Clusters
Michael Hilker
In this contribution, first results of deep VLT photometry (V,I) in the central region of the Hydra I and Centaurus galaxy clusters are presented. In both galaxy clusters, many sta…
