论文摘要
标量张量矢量重力（STVG）是一种完全协变量的洛伦兹不变的重力理论，也称为修饰重力（MOG），它通过动态的巨大矢量场和标量场修饰了一般相对性（GR）。在STVG中，向量场$ ϕ $的质量$μ$，通用引力常数G具有动态场的状态。我们使用XMM-Newton望远镜从X射线观察中获得的重建总簇质量，以及在Planck All-Sky调查中观察到的Sunyaev-Zel'Dovich（SZ）效应，以估计参数$α$和$ $ $ $α$和$ $ $与MOG中的群集质量。
Scalar Tensor Vector Gravity(STVG) is a fully covariant Lorentz invariant alternative theory of gravity also called as MOdified Gravity(MOG) which modifies General Relativity(GR) with dynamical massive vector field and scalar fields. In STVG the mass $μ$ of the vector field $ϕ$ and the Universal gravitational constant G enjoys the status of a dynamical field. We use the reconstructed total cluster mass obtained from X-ray observations by XMM-Newton telescope in combination with the Sunyaev-Zel'dovich(SZ) effect observed within Planck all-sky survey to estimate the parameters $ α$ and $μ$ with modified cluster mass in MOG.
