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…

Physical morphology and triggers of starburst galaxies
C. J. Conselice, M. A. Bershady, J. S. Gallagher
We present a method of determining the likely triggering mechanisms for luminous, nearby starbursts based on their optical asymmetry and (B-V) color -- what we term as indices of `…
