Spectroscopy of Abell 222 and Abell 223

This spectroscopic study of the neighboring massive clusters Abell 222 and Abell 223 is based on MOS using EMMI at the NTT. Photometry was obtained from WFI images taken with...本项针对邻近大质量星系团阿贝尔222（Abell 222）与阿贝尔223（Abell 223）的光谱学研究，依托安装于新技术望远镜（NTT, New Technology Telescope）的EMMI设备开展的多目标光谱观测（MOS, Multi-Object Spectroscopy）完成。测光数据取自广角成像仪（WFI, Wide Field Imager）所拍摄的图像……
