[13.02U] Modeling the Dark Matter Halo Properties of Cluster Galaxies

M. Eftimova (DePaul University), D.A. Dale (University of Wyoming)

Using the H\alpha rotation curves and I band profiles of over 500 high surface brightness cluster galaxies, we have modeled the disk mass-to-light ratio, dark matter halo central density, and halo core radius. The distribution of the fitted parameters, and dependencies with cluster-centric distance, are presented and discussed.
