A search for ultra-compact dwarf galaxies in the Centaurus galaxy cluster
S. Mieske, M. Hilker, A. Jordan +2
Aim: To extend the investigations of ultra-compact dwarf galaxies (UCDs) beyond the well studied Fornax and Virgo clusters. Methods: We measured spectroscopic redshifts of about 40…
Dynamical masses of ultra-compact dwarf galaxies in Fornax
M. Hilker, H. Baumgardt, L. Infante +3
Aims. We determine masses and mass-to-light ratios of five ultra-compact dwarf galaxies and one dwarf elliptical nucleus in the Fornax cluster from high resolution spectroscopy. Me…
Dwarf galaxies in the Antlia Cluster: First results
A. V. Smith Castelli, L. P. Bassino, S. A. Cellone +5
We present the first results of a project aimed to study the galaxy population of the Antlia cluster, the third nearest galaxy cluster after Virgo and Fornax. The observations for…
Spectroscopic metallicities for Fornax UCDs, GCs and dE,Ns
S. Mieske, M. Hilker, L. Infante +1
Various formation channels for the puzzling ultra-compact dwarf galaxies (UCDs) have been proposed in the last few years. To better judge on some of the competing scenarios, we pre…
UCDs in Fornax and Abell 1689
S. Mieske, M. Hilker, L. Infante
We review some properties of ultracompact dwarf galaxies (UCDs) in Fornax and of their brighter counterparts in Abell 1689, among which are two M32 twins, and discuss various possi…
The distance to Hydra and Centaurus from surface brightness fluctuations: Consequences for the Great Attractor model
S. Mieske, M. Hilker, L. Infante
We present I-band Surface Brightness Fluctuations (SBF) measurements for 16 early type galaxies (3 giants, 13 dwarfs) in the central region of the Hydra cluster, based on deep phot…
