The Chemical Evolution of Galaxies: The Stellar Mass-Metallicity Relation
F. D. A. Hartwick
The predictions of the multiple burst accretion model of chemical evolution are compared to the observations of the stellar masses and metallicities of star-forming galaxies. With…
A multiple burst accretion Model to describe the metallicity distributions and stellar mass-metallicity relation for Local Dwarf Galaxies
F. D. A. Hartwick
A one parameter model to describe the individual metallicity distributions and stellar mass-metallicity relation for dwarf galaxies is presented. This multiple-burst model is based…
Early Type Galaxy Core Phase Densities
R. G. Carlberg, F. D. A. Hartwick
Early type galaxies have projected central density brightness profile logarithmic slopes, gamma^prime, ranging from about 0 to 1. We show that gamma^prime is strongly correlated, r…
Super-Massive Stars as a Source of Abundance Anomalies of Proton-Capture Elements in Globular Clusters
Pavel A. Denissenkov, F. D. A. Hartwick
We propose that the abundance anomalies of proton-capture elements in globular clusters, such as the C-N, Na-O, Mg-Al and Na-F anti-correlations, were produced by super-massive sta…
Modelling Observational Constraints for Dark Matter Halos
F. D. A. Hartwick
Observations show that the underlying rotation curves at intermediate radii in spiral and low-surface brightness galaxies are nearly universal. Further, in these same galaxies, the…
The Velocity Field Around Groups of Galaxies
F. D. A. Hartwick
A statistical method is presented for determining the velocity field in the immediate vicinity of groups of galaxies using only positional and redshift information with the goal of…
