Uncertainties in Galaxy Rotation Curves
J A Sellwood, Kristine Spekkens, Carter S. Eckel
Assessing the likelihood that the rotation curve of a galaxy matches predictions from galaxy formation simulations requires that the uncertainties in the circular speed as a functi…
Non-parametric decompositions of disk galaxies in SG using DiskFit
Colin Lewis, Kristine Spekkens
We present photometric models of 532 disk galaxies in 3.6μm images from the Spitzer Survey of Stellar Structure in Galaxies (SG) using the non-parametric DiskFit algorithm. We…
Simulating a slow bar in the low surface brightness galaxy UGC 628
Matthew H. Chequers, Kristine Spekkens, Lawrence M. Widrow +1
We present a disc-halo N-body model of the low surface brightness galaxy UGC 628, one of the few systems that harbours a "slow" bar with a ratio of corotation radius to bar length…
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…
DiskFit: a code to fit simple non-axisymmetric galaxy models either to photometric images or to kinematic maps
J. A. Sellwood, Kristine Spekkens
This posting announces public availability of version 1.2 of the DiskFit software package developed by the authors, which may be used to fit simple non-axisymmetric models either t…
