DescriptionKinematic measurements of galaxies provide a way to trace their mass distributions. The RSS Imaging spectroscopy Nearby Galaxy Survey (RINGS) was designed to probe the mass distributions of 19 spiral galaxies on small spatial scales by obtaining a suite of multi-wavelength kinematic and photometric data. In this dissertation, I introduce the high-spatial-resolution, medium-spectral-resolution Hα kinematic portion of the survey, and detail the process which has been used to convert the raw Fabry-P´erot observations into useful kinematic data and models. These Hα kinematic data were obtained with the Robert Stobie Spectrograph (RSS) at the Southern African Large Telescope (SALT). I then demonstrate how these Hα kinematic data can be combined with the other types of observations in RINGS, H I radio interferometry and broadband photometric imaging, to probe these galaxies’ mass distributions.
