We present results on the stellar populations in field galaxies observed as part of the observations for the Gemini/HST Galaxy Cluster project. Our analysis is based on high signal-to-noise spectra in rest frame 3700Å to 5400Å. We focus on the relations between the galaxy internal velocity dispersions and the absorption line indices CN3883, Mgb, and several indices for Balmer lines and iron lines. The properties of the field galaxies are compared to those of cluster galaxies at similar redshifts.
This poster is presented by the PI of the Gemini/HST Galaxy Cluster project on behalf of students at University of Oregon. The project serves as a research project for the student group.
