MG-MAMPOSSt，一个在星系团尺度上检验重力的程序：技术介绍
MG-MAMPOSSt, a code to test gravity at galaxy-cluster scales: a technical introduction
摘要：
\textsc{MG-MAMPOSSt}代码是一个免许可证的\textsc{Fortran95}代码，用于通过分析基于Jeans方程的星系团的运动学数据来执行广义相对论（GR）的测试。该代码是基于\textsc{MAMPOSSt}方法，并扩展了原来的代码，通过新的参数化的一般家庭的引力理论以外的GR旨在解释暗能量的引力势。\textsc{MG-MAMPOSSt}进一步补充了一个新的能力，以产生联合运动学+透镜分析的弱透镜预测。本文档提供了代码的新特性、相对于原始版本的功能的技术描述，以及关于其安装和使用的说明。最后，我们解释了如何进一步修改代码，以包括更广泛的家庭的重力模型和/或密度分布，这可以使其应用在更广泛的理论框架以及其他物理系统，如星团。Pizzuti等人的论文中对目前代码中实施的修改后的重力模型进行了详细的预测分析，2021.
英文摘要：
The \textsc{MG-MAMPOSSt} code is a license-free \textsc{Fortran95} code to perform tests of General Relativity (GR) through the analyses of kinematical data of galaxy clusters based on the Jeans' equation. The code is based on the \textsc{MAMPOSSt} method, and extends the original code through new parametrisations of the gravitational potential for general families of gravity theories beyond GR aimed to explain dark energy. \textsc{MG-MAMPOSSt} is further supplemented with a new capability to produce weak lensing forecasts for joint kinematic+lensing analysis. This document provides a technical description of the code's new features, functionality with respect to the original version, and instructions on its installation and use. Finally, we explain how the code could be further modified to include a wider family of gravity models and/or density profiles, that could allow its application in broader theoretical frameworks as well as other physical systems such as stellar clusters. A detailed forecast analysis for the modified gravity models currently implemented in the code can be found in the paper of Pizzuti et al., 2021.
