The aim of this project is to extend the GALFORM semi-analytical model of galaxy formation to predict the formation and evolution of galaxies in a modified gravity cosmology. Such models are competitors to the standard model in which gravity is described by general relativity. A change to the law of gravity can potentially change the structure and spin of dark matter halos, the merger history of dark matter halos, the rate at which gas cools, the dynamics of galaxies and the evolution of their stellar populations. The results of the project will be used to make mock galaxy surveys for DESI and Euclid.

这个项目的目的是扩展星系形成的GALFORM半解析模型，以预测修正引力宇宙学中星系的形成和演化。这些模型是广义相对论描述重力的标准模型的竞争对手。引力定律的改变可能会改变暗物质晕的结构和自转、暗物质晕的合并历史、气体冷却的速度、星系的动力学及其恒星群的演化。该项目的结果将用于对DESI和Euclid进行模拟星系观测。
