Modeling Non-Circular Motions in Disk Galaxies: A Bar in NGC 2976
K. Spekkens, J. A. Sellwood
We give a brief description of a new model for non-circular motions in disk galaxy velocity fields, that does not invoke epicycles. We assume non-circular motions to stem from a ba…

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…
