The Photometric Properties of Isolated Early-Type Galaxies (2004)
Reda, Fatma M., Forbes, Duncan A., Beasley, Michael A., O'Sullivan, Ewan J., Goudfrooij, Paul
Isolated galaxies are important since they probe the lowest density regimes inhabited by galaxies. We define a sample of 36 nearby isolated early-type galaxies for further study. Our isolation...

Beasley, Michael A., Harris, William E., Harris, Gretchen L. H., Forbes, Duncan A.
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 obtained from...
Forming Globular Cluster Systems in a Semi-analytic Scheme (2002)
Beasley, Michael A., Baugh, Carlton M., Forbes, Duncan A., Sharples, Ray M., Frenk, Carlos S.
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 the model allows us...
Testing Stellar Population Models with Star Clusters in the Large Magellanic Cloud (2002)
Beasley, Michael A., Hoyle, Fiona, Sharples, Ray M.
We present high S/N integrated spectra of 24 star clusters in the LMC obtained using the FLAIR spectrograph at the UK Schmidt. The spectra have been placed onto the Lick/IDS system in order to test...
Beasley, Michael A., Bekki, Kenji, Couch, Warrick J., Forbes, Duncan A.
We investigate the spatial, kinematic and chemical properties of globular cluster systems formed in merging and interacting galaxies using N-body-smoothed particle hydrodynamics (SPH) simulations....

Age Estimates for Globular Clusters in NGC 1399 (2001)
Forbes, Duncan A., Beasley, Michael A., Brodie, Jean P., Kissler-Patig, Markus
We present high signal-to-noise Keck spectra for 10 globular clusters associated with the giant Fornax elliptical NGC 1399, and compare measured line indices with current stellar population models....
