Maximal Halos in High-Luminosity Spiral Galaxies

Abstract

We test the halo dominated mass model, recently proposed for high-luminosity galaxies by Courteau & Rix (1998), against rotation velocity data for a large sample of L_* spirals. We find that this model does not reproduce the general kinematic properties required. The alternative disc dominated model, on the contrary, easily fits the data.
