The RINGS Survey III: Medium-Resolution Halpha Fabry-Perot Kinematic Dataset
Carl J. Mitchell, J. A. Sellwood, T. B. Williams +3
The distributions of stars, gas, and dark matter in disk galaxies provide important constraints on galaxy formation models, particularly on small spatial scales (<1kpc). We have de…
The RINGS Survey: High-Resolution H-alpha Velocity Fields of Nearby Spiral Galaxies with the SALT Fabry-Perot
Carl J. Mitchell, J. A. Sellwood, T. B. Williams +3
We have obtained high-spatial-resolution spectrophotometric data on several nearby spiral galaxies with the Southern African Large Telescope (SALT) Fabry-Pérot interferometer on th…
The RINGS Survey I: Halpha and HI Velocity Maps of Galaxy NGC 2280
Carl J. Mitchell, T. B. Williams, Kristine Spekkens +3
Precise measurements of gas kinematics in the disk of a spiral galaxy can be used to estimate its mass distribution. The Southern African Large Telescope (SALT) has a large collect…
Searching for Non-axisymmetries in NGC 6503: A Weak End-on Bar
Rachel Kuzio de Naray, Cameron A. Arsenault, Kristine Spekkens +4
The isolation, simple apparent structure, and low luminosity of the nearby spiral galaxy NGC 6503 make it an ideal candidate for an in-depth kinematic and photometric study. We int…
A Test for Radial Mixing Using Local Star Samples
Jincheng Yu, J. A. Sellwood, Carlton Pryor +2
We use samples of local main-sequence stars to show that the radial gradient of [Fe/H] in the thin disk of the Milky Way decreases with mean effective stellar temperature. Many of…
Modeling Non-Circular Motions in Disk Galaxies: Application to NGC 2976
Kristine Spekkens, J. A. Sellwood
We present a new procedure to fit non-axisymmetric flow patterns to 2-D velocity maps of spiral galaxies. We concentrate on flows caused by bar-like or oval distortions to the tota…
