Globular Cluster Abundances from High-Resolution, Integrated-Light Spectroscopy. II. Expanding the Metallicity Range for Old Clusters and Updated Analysis Techniques
J. E. Colucci, R. A. Bernstein, A. McWilliam
We present abundances of globular clusters in the Milky Way and Fornax from integrated light spectra. Our goal is to evaluate the consistency of the integrated light analysis relat…
The Detailed Chemical Properties of M31 Star Clusters I. Fe, Alpha and Light Elements
J. E. Colucci, R. A. Bernstein, J. Cohen
We present ages, [Fe/H] and abundances of the alpha elements Ca I, Si I, Ti I, Ti II, and light elements Mg I, Na I, and Al I for 31 globular clusters in M31, which were obtained f…
Evidence for Two Distinct Stellar Initial Mass Functions : Probing for Clues to the Dichotomy
Dennis Zaritsky, Janet E. Colucci, Peter M. Pessev +2
We present new measurements of the velocity dispersions of eleven Local Group globular clusters using spatially integrated spectra, to expand our sample of clusters with precise in…
Chemical Abundance Evidence of Enduring High Star Formation Rates in an Early Type Galaxy: High [Ca/Fe] in NGC 5128 Globular Clusters
J. E. Colucci, M. F. Duran, R. A. Bernstein +1
We present [Fe/H], ages, and Ca abundances for an initial sample of 10 globular clusters in NGC 5128 obtained from high resolution, high signal-to-noise ratio echelle spectra of th…
Evidence for Two Distinct Stellar Initial Mass Functions : Revisiting the Effects of Cluster Dynamical Evolution
Dennis Zaritsky, Janet E. Colucci, Peter M. Pessev +2
We measure the velocity dispersions of six, galactic globular clusters using spatially integrated spectra, to test for the effects of internal dynamical evolution in the stellar ma…
Extragalactic Globular Cluster Populations from High Resolution Integrated Light Spectra
J. E. Colucci, R. A. Bernstein, A. McWilliam +1
We present a comparison of high-resolution, integrated-light, detailed chemical abundances for Galactic and extragalactic globular clusters in both massive galaxies and dwarf galax…
