A Robust Method for the Analysis of Integrated Spectra from Globular Clusters using Lick Indices
Robert N. Proctor, Duncan A. Forbes, Michael A. Beasley
We define a method for analysis of the integrated spectra of extra-galactic globular clusters that provides more reliable measures of age, metallicity and alpha-element abundance r…
Gemini/GMOS Imaging of Globular Clusters in the Virgo Galaxy NGC 4649 (M60)
Duncan A. Forbes, Favio Raul Faifer, Juan Carlos Forte +6
We present Sloan g and i imaging from the GMOS instrument on the Gemini North telescope for the globular cluster (GC) system around the Virgo galaxy NGC 4649 (M60). Our three point…
The Metallicity of Pre-Galactic Globular Clusters: Observational consequences of the first stars
Michael A. Beasley, Daisuke Kawata, Frazer. R. Pearce +2
We explore a scenario where metal-poor globular clusters (GCs) are enriched by the first supernovae in the Universe. If the first stars in a 10^7 Msun dark halo were very massive (…
