Neutral Hydrogen in Galaxy Groups
N. P. F. McKay, C. G. Mundell, S. Brough +2
We present preliminary results from a study of the neutral hydrogen (HI) properties of an X-ray selected sample of nearby loose galaxy groups. This forms part of a multi-wavelength…
Spectroscopy of Globular Clusters in the Fornax dwarf galaxy
Jay Strader, Jean P. Brodie, Duncan A. Forbes +2
We present low resolution, integrated Keck spectra of the five globular clusters (GCs) of the Fornax dwarf spheroidal galaxy. We find a tentative age spread among the clusters, wit…
Simultaneous Modelling of the Stellar Halo and Globular Cluster System of NGC 5128
Michael A. Beasley, William E. Harris, Gretchen L. H. Harris +1
An important test for models of galaxy formation lies in the metallicity distribution functions (MDFs) of spheroid stars and their globular clusters (GCs).We have compared the MDFs…
Evidence for An Intermediate-Age, Metal-rich Population of Globular Clusters in NGC 4365
S. S. Larsen, J. P. Brodie, M. A. Beasley +4
We present spectroscopy for globular clusters (GCs) in the elliptical galaxy NGC 4365, obtained with the LRIS spectrograph on the Keck I telescope. Previous studies have shown that…
Forming Globular Cluster Systems in a Semi-analytic Scheme
Michael A. Beasley, Carlton M. Baugh, Duncan A. Forbes +2
We apply the semi-analytical galaxy formation code of Cole et al. to investigate the formation of globular cluster (GC) systems in hierarchical clustering scenarios. The nature of…
Observational Properties of Extragalactic Globular Cluster Systems
Duncan A. Forbes
The superior resolution of HST and the light gathering power of large 8-10m class telescopes are now providing information on distant globular clusters (GCs) that is comparable to…
