This paper addresses available constraints on mass models fitted to rotation curves. Mass models of disk galaxies have well-known degeneracies that prevent a unique mass decomposition. The most notable is due to the unknown value of the stellar mass-to-light ratio (the disk-halo degeneracy); even with this known, degeneracies between the halo parameters themselves may prevent an unambiguous determination of the shape of the dark halo profile, which includes the inner density slope of the dark… Expand
A REVISED MODEL FOR THE FORMATION OF DISK GALAXIES: LOW SPIN AND DARK HALO EXPANSION
We use observed rotation velocity-luminosity (VL) and size-luminosity (RL) relations to single out a specific scenario for disk galaxy formation in the ΛCDM cosmology. Our model involves fourExpand

We explore the dependence of the ratio of a galaxy's maximum circular velocity, Vc, to its central velocity dispersion, σ0, on morphology or, equivalently, total light concentration. Such aExpand
Biases in inferring dark matter profiles from dynamical and lensing measurements
