用显著统计量打破晕占据简并
Breaking Halo Occupation Degeneracies with Marked Statistics
摘要:
我们表明,一个适当定义的标记关联函数可以用来打破退化晕占领分布建模。统计数据可以在3D和2D数据集上计算,并且应该适用于所有即将到来的星系调查。一个证明的原则,使用模拟目录从N体模拟,给出。
英文摘要:
We show that a suitably defined marked correlation function can be used to break degeneracies in halo-occupation distribution modeling. The statistic can be computed on both 3D and 2D data sets, and should be applicable to all upcoming galaxy surveys. A proof of principle, using mock catalogs created from N-body simulations, is given.
