论文摘要
我们提出\ textsc {mg-mamposst}，这是一种无许可证代码，可通过使用集群成员星系的运动学来重建星系簇的质量分布来限制修改的重力模型。我们描述了代码的主要特征，当运动信息与镜头数据结合使用时，我们显示了该方法的能力。我们讨论了当前在代码中实施的两类模型的最新结果和预测，其特征是不同的筛选机制，即变色龙和Vainshtein筛选。我们进一步探讨了可能的系统技术对即将进行的调查的数据的应用。该程序总结了2021年9月在Altecosmofun研讨会上提出的结果。
We present \textsc{MG-MAMPOSSt}, a license-free code to constrain modified gravity models by reconstructing the mass profile of galaxy clusters with the kinematics of the cluster's member galaxies. We describe the main features of the code and we show the capability of the method when the kinematic information is combined with lensing data. We discuss recent results and forecasts on two classes of models currently implemented in the code, characterized by different screening mechanisms, namely, chameleon and Vainshtein screening. We further explore the impact of possible systematics in view of application to the data from upcoming surveys. This proceedings summarizes the results presented at the ALTECOSMOFUN workshop in September 2021.
