| Abstract: |
The growth and distribution of galaxy stellar components in dark matter halos is one of the fundamental concepts in current ΛCDM models. An ongoing project correlating structural properties of galaxy disks to the distribution of dark matter will enhance our understanding of how dark matter halos affect the formation and evolution of galaxy disks. NGC 4088 is one target from a statistical sample of nearby galaxies that will be used to investigate correlations between dark matter content and underlying structure. 21-cm line observations of HI are used for the dynamical analysis, and when combined with Spitzer 3.6-μm data, yield a dark matter mass fraction. Optical B, R, and Hα observations provide information about the dominant stellar population and current star formation rate. The combination of optical, near-infrared, and HI-synthesis observations will enable a comprehensive analysis of the evolution of galactic disks as a function of baryonic mass, environment, and dark matter mass. |
