Abstract: By constructing a large, uniform galaxy cluster catalog from the SDSS data, we have found that cluster galaxies evolve both spectrally and morphologically. By studying the morphology--cluster-centric-radius relation, we have found two characteristic environments where galaxy morphologies change dramatically. We found passive spiral galaxies in the infalling region of clusters. They are likely to be a galaxy population in transition due to the cluster environment. We also studied E+A galaxies, which have also been thought to be cluster originated. We found that E+As live in all environments including the field region.
