Galaxy Kinematics with SALT
Matthew A. Bershady, Marc A. W. Verheijen, David R. Andersen +2
The combination of dynamical and photometric properties of galaxies offers a largely un-tapped source of information on how galaxies assembled and where stars formed. Bi-dimensiona…
The Kinematics in the Cores of Low Surface Brightness Galaxies
R. A. Swaters, M. A. W. Verheijen, M. A. Bershady +1
Systematic effects on HI and Halpha long-slit observations make a measurement of the inner slope of the dark matter density distribution difficult to determine. Halos with constant…
WIYN Integral-Field Kinematics of Disk Galaxies
Matthew Bershady, Marc Verheijen, David Andersen
We have completed a new fiber array, SparsePak, optimized for low-surface-brightness studies of extended sources on the WIYN telescope. We are now using this array as a measuring e…
The Intrinsic Ellipticity of Spiral Disks
David R. Andersen, Matthew A. Bershady
We have measured the distribution of intrinsic ellipticities for a sample of 28 relatively face-on spiral disks. We combine H-alpha velocity fields and R and I-band images to deter…
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…
