Spectroscopy of galaxy clusters to find LCBGs

We used the DEIMOS spectrograph on the Keck II Telescope to obtain spectra of galaxies in the fields of five distant, rich galaxy clusters over the redshift range 0.5本研究利用凯克Ⅱ望远镜（Keck II Telescope）上搭载的DEIMOS光谱仪（DEIMOS Spectrograph），对红移区间为0.5的5个遥远富星系团天区内的星系获取了光谱观测数据。
