This study focuses on the identification and investigation of clumpy galaxies in the Extended Groth Strip using GALFIT and nonparametric methods with James Webb Space Telescope data from the CEERS survey. Visual classification identified 108 clumpy galaxies, and a random sampling estimated approximately 48% of galaxies exhibit clumpy structures. GALFIT parametric decomposition showed most clumps are modeled by an exponential light distribution with an average Sérsic index of n≈1, but some exhibited higher values up to 8.9, indicating a central concentration possibly related to massive black holes or increased star formation. This research aims to contribute valuable insight into the structural characteristics of clumpy galaxies, enhancing understanding of galaxy morphology and evolution.
