Morphological analysis of well-resolved galaxies

We have developed a Python-based tool for the detailed morphological analysis of well-resolved galaxies. Our method removes foreground stars, determines the position and inclination angles, fits structural components for spiral galaxies, models the radial light profile, and transforms the image into polar coordinates to produce a Theta–log(r) representation. We then measure the opening angles of the spiral arms and analyze the power spectrum and flocculence of the galactic disk to determine the strength of the spiral structure.
