The specific frequencies of ultra-compact dwarf galaxies
Steffen Mieske, Michael Hilker, Ingo Misgeld
We aim at quantifying the specific frequency of UCDs in a range of environments and at relating this to the frequency of globular clusters (GCs) and potential progenitor dwarf gala…
A deep view on the Virgo cluster core
Stefan Lieder, Thorsten Lisker, Michael Hilker +2
In this study we investigate the optical photometric properties of early-type galaxies in the Virgo cluster core region, by analysing their location on the colour magnitude relatio…
Families of dynamically hot stellar systems over ten orders of magnitude in mass
I. Misgeld, M. Hilker
Dynamically hot stellar systems, whether star clusters or early-type galaxies, follow well-defined scaling relations over many orders of magnitudes in mass. These fundamental plane…
A large population of ultra-compact dwarf galaxies in the Hydra I cluster
I. Misgeld, S. Mieske, M. Hilker +3
We performed a large spectroscopic survey of compact, unresolved objects in the core of the Hydra I galaxy cluster (Abell 1060), with the aim of identifying ultra-compact dwarf gal…
The dark halo of the Hydra I galaxy cluster: core, cusp, cosmological? Dynamics of NGC 3311 and its globular cluster system
T. Richtler, R. Salinas, I. Misgeld +5
NGC 3311 is the central cD galaxy of the Hydra I cluster. We use globular clusters around NGC 3311, combined with kinematical data of the galaxy itself, to investigate the dark mat…
