dc.description.abstractPure disk galaxies are galaxies that form and evolve without a central bulge region. This morphology of galaxy is relatively unexplained and has yet to be successfully simulated using Lambda-Cold Dark Matter (ΛCDM) model parameters. The ΛCDM model is the standard framework from which astronomers and physicists understand and predict the Universe due to confirmed predictions such as the cosmic microwave background and the large scale structure of galaxy clusters. However, ΛCDM has yet to have a benchmark, observationally confirmed prediction on the galactic scale. This thesis is a study of eleven pure disk galaxies. Understanding this type of galaxy is very important in rectifying the incompatibility with the ΛCDM model. The method of analysis includes obtaining, cleaning and sky subtracting images from the Sloan Digital Sky Survey Data Release 7, deprojecting the images for a face on perspective, using g- and i-bands to construct color-index maps, using Fourier decompositions to create mode-dependent intensity ratio plots, surface density maps, mass-to-light ratio maps and surface brightness profiles, from which the radial scale length is derived. The future of this area of study is vital to understand a common feature of our Universe. Future studies can include looking for early supernova remnants or evidence of recent active galactic nuclei activity in young pure disk galaxies. Surveys and photometric analysis of edge-on pure disk galaxies may also reveal vital information to the origin and evolution of this class of galaxy.en_US
