Mass decomposition of spiral galaxies from disc kinematics

Abstract

Summary We devise a method for the disc/halo mass decomposition of the rotation curves of spiral galaxies that was outlined by us in a previous paper. Upon application to a larger sample of 58 spirals, we confirm our earlier results. In particular, we find that the disc-to-halo mass ratio at the optical radius, Mdisc/Mhalo, is a strong function of luminosity, Mdisc/Mhalo α LB2/3.
