H-alpha Velocity Fields of Normal Spiral Disks

David R. Andersen, M. A. Bershady, L. S. Sparke +4

We present H-alpha velocity fields for a sample of nearly face--on spiral galaxies observed with DensePak on the WIYN telescope. We combine kinematic inclinations and position angl…

The Assembly and Evolution of Spiral Disks

Matthew Bershady, David Andersen

We explore how the growth rate of spiral disks can be measured via analyses of the scatter in the Tully-Fisher (TF) relation of local and intermediate redshift galaxies. As an init…
