Recent constraints on the splashback radius around optically selected galaxy clusters from the redMaPPer cluster-finding algorithm in the literature have shown that the observed splashback radius is $\sim 20\%$ smaller than that predicted by N-body simulations. We present analyses on the splashback features around $\sim 3000$ optically selected galaxy clusters detected by the independent cluster-finding algorithm CAMIRA over a wide redshift range of $0.1

斯巴鲁 HSC 第二次公开数据发布的光学选择集群的飞溅半径

最近，文献中 redMapPer 星团寻找算法对光学选择的星系团周围的飞溅半径的限制表明，观察到的飞溅半径比 N 体模拟预测的小 $\sim 20\%$。我们对独立星团寻找算法 CAMIRA 在 0.1 美元的宽红移范围内检测到的 $\sim 3000$ 光学选择的星系团周围的飞溅特征进行了分析
