Abstract

We applied a method identified by Puerari & Dottori (1997) to find the corotation radii of 57 galaxies. This entailed taking Fourier transforms along radial cuts in the u, g, r, i, and z wavebands and comparing the phase angles as a function of radius between them. The radius at which the phase angles cross indicates the location of the corotation radius. We then calculated the relative bar pattern speed, R and classified the bar as fast, less than 1.4, or slow, greater than or equal to 1.4. Finally, we found that our results were consistent with previously determined values of R obtained by the computer simulations of Rautiainen et al. (2008).
