Observational constraints on disk galaxy formation
D. Syer, Shude Mao, H. J. Mo
We use data from the literature to constrain theoretical models of galaxy formation. We show how to calculate the dimensionless spin parameter of the halos of disk galaxies and…

Global stability and the mass-to-light ratio of galactic disks
D. Syer, Shude Mao, H. J. Mo
We examine the global stability of an exponential stellar disk embedded in a dark matter halo and constrain the mass-to-light ratio of observed disks in the I-band, Y_I. Assuming o…
