Fundamental stellar & halo data for local galaxies

We then exploit such templates to determine fundamental stellar and halo properties for a sample of about 550 local disk-dominated galaxies with high-quality measurements of the optical radius R_opt_ and of the corresponding rotation velocity V_opt_.

Specifically, we determine the stellar M_*_ and halo M_H_ masses, the halo size R_H_ and velocity scale V_H_, and the specific angular momenta of the stellar j_*_ and dark matter j_H_ components. We derive global scaling relationships involving such stellar and halo properties both for the individual galaxies in our sample and for their mean within bins; the latter are found to be in pleasing agreement with previous determinations by independent methods (e.g., abundance matching techniques, weak-lensing observations, and individual rotation curve modeling).
