我们发展了一个新的理论，星系团在一个不断膨胀的宇宙。它是基于热力学的引力系统，并适用于强集群的高度非线性制度。在这个理论的最简单形式中没有自由参数。它预测了所有阶数的分布函数，从空洞到数百个星系。数值N体实验的结果与这些预测的比较显示出实质性的协议。与观测到的星系分布进行比较，可以确定它是否具有非松弛结构，保留了宇宙中更容易的时代的信息。
We develop a new theory for galaxy clustering in an expanding universe. It is based on the thermodynamics of gravitating systems and applies to the highly nonlinear regime of strong clustering. There are no free parameters in the simplest form of this theory. It predicts distribution functions of all orders, from voids to hundreds of galaxies. Comparison of these predictions with the results of numerical N-body experiments shows substantial agreement. Comparison with the observed distribution of galaxies may determine whether it has unrelaxed structure that retains information from much easier epochs of the universe.
