Faint dwarf spheroidals in the Fornax Cluster: A flat luminosity function
Michael Hilker, Steffen Mieske, Leopoldo Infante
We have discovered about 70 very faint dwarf galaxies in the Fornax Cluster. These dSphs candidates follow the same magnitude-surface brightness relation as their counterparts in t…
Globular Clusters in nearby Galaxy Cluster
Michael Hilker
The discovery of a large population of intra-cluster star clusters in the central region of the Hydra I and Centaurus galaxy clusters is presented. Based on deep VLT photometry (V,…
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…
Extragalactic Globular Clusters in the Near-Infrared II. The Globular Clusters Systems of NGC 3115 and NGC 4365
Thomas H. Puzia, Stephen E. Zepf, Markus Kissler-Patig +3
We combine near-infrared photometry obtained with the VLT/ISAAC instrument and archival HST/WFPC2 optical images to determine VIK magnitudes and colours of globular clusters in two…
Ultra Compact Objects in the Fornax Cluster of Galaxies: Globular clusters or dwarf galaxies?
Steffen Mieske, Michael Hilker, Leopoldo Infante
The relation between the Ultra Compact Objects (UCOs) recently discovered in the Fornax cluster (Drinkwater et al. 2000, Hilker et al. 1999) and the brightest globular clusters ass…
