Quantitative analysis of the morphology of galaxies using visible and infrared data has been extensively studied by Conselice (2003) and others. On the other hand, quantitative analysis of the distribution of molecular gas in nearby galaxies, which is essential for studying galaxy evolution, has not been sufficiently carried out due to the lack of spatial resolution. However, with the operation of ALMA, a large amount of high-resolution molecular gas observation data has been accumulated. This has made it possible to do equivalent to Conselice’s research. We established a specific procedure to calculate the Concentration (C), Asymmetry (A), and Clumpiness (S) values for each galaxy by applying Conselice's method and have done the analyses. In this poster, we report the results of that analysis. This study is not limited to nearby galaxies. It has the potential to be applied to high-redshift galaxies.
