The Chemical Properties of Milky Way and M31 Globular Clusters: II. Stellar Population Model Predictions

Michael A. Beasley, Jean P. Brodie, Jay Strader +4

We derive ages, metallicities and [alpha/Fe] ratios from the integrated spectra of 23 globular clusters in M31, by employing multivariate fits to two stellar population models. In…

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…

Probing Spectral Line Gradients Beyond One Effective Radius in NGC 3610

Justin Howell, Jean Brodie, Jay Strader +2

The outer region (0.75--1.25 r_e in the B-band) of the merger-remnant elliptical NGC 3610 is studied using extremely high signal to noise Keck spectra, with a supplementary spectru…

The Chemical Properties of Milky Way and M31 Globular Clusters: I. A Comparative Study

Michael A. Beasley, Jean P. Brodie, Jay Strader +4

A comparative analysis is performed between high-quality integrated spectra of 30 globular clusters in M31, 20 Milky Way clusters, and a sample of field and cluster elliptical gala…

Ages and Metallicities of Hickson Compact Group Galaxies

Robert N. Proctor, Duncan A. Forbes, George K. T. Hau +4

Hickson Compact Groups (HCGs) constitute an interesting extreme in the range of environments in which galaxies are located, as the space density of galaxies in these small groups a…
