论文摘要
我们利用了Finzi提出的一种新的重力理论，该理论在大尺度上提供了更强的相互作用，以研究星系簇的热力学描述。我们采用统计模型来推断各种状态的热力学方程。此外，我们与其标准（牛顿）对应物相比，分析了聚类参数的行为。还研究了一般分布函数及其具有不同强度的聚类参数的行为。研究了相变的可能性，并且观察到尽管层次上是可能的。我们还通过将结果与通过SDSS-III可用的数据进行比较，并获得所涉及的参数来分析模型。
We exploit a new theory of gravity proposed by Finzi, which gives stronger interaction at large scales, to study the thermodynamic description of galaxy clusters. We employ a statistical model to deduce various thermodynamics equations of state. In addition, we analyze the behavior of clustering parameter in comparison to its standard (Newtonian) counterpart. The general distribution function and its behavior with varying strength of clustering parameter are also studied. The possibility of phase transition is investigated and it is observed that a phase transition is possible though hierarchically. We also analyze the model by comparing the results with data available through SDSS-III, and obtain the parameters involved.
