Rich galaxy clusters richness-based masses

We present a catalog of galaxy cluster masses derived by exploiting the tight correlation between mass and richness, i.e., a properly computed number of bright cluster galaxies....本研究提出了一套星系团（galaxy cluster）质量目录，该目录通过利用星系团质量与丰度（richness）之间的紧密相关性推导得到，其中丰度即经合理计算的亮星系团成员星系数量。
