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…
