Imaging and spectroscopy in three galaxy clusters

We present an analysis of stellar populations and evolutionary history of galaxies in three similarly rich galaxy clusters MS0451.6-0305 (z=0.54), RXJ0152.7-1357 (z=0.83), and...本文针对三个富度相当的星系团MS0451.6-0305（红移z=0.54）、RXJ0152.7-1357（红移z=0.83）及其他星系团中的星系，开展恒星族群与演化历史的分析。
