How dark matter influences the formation and evolution of galaxies is to this day an outstanding question in astrophysics. To answer it, world-class facilities and a unique combination of observations and theory are required. This DP team, a world-class team of observers and theorists, will tackle this question by leveraging on two multi-million dollar projects: the MAGPI galaxy survey and the hydrodynamical simulations suite EAGLE-XL. MAGPI will deliver exquisite kinematics for hundreds of galaxies in the middle ages of the Universe, providing a view to the effect of dark matter on galaxies at this critical time, while EAGLE-XL represents the technological frontier in simulations and provides the best interpretative framework for MAGPI.

暗物质如何影响星系的形成和演化，至今仍是天体物理学中一个突出的问题。要回答这个问题，需要世界一流的设施和独特的观测与理论相结合。这个DP团队是一个世界级的观察员和理论家团队，将通过利用两个数百万美元的项目来解决这个问题：MAGPI星系调查和流体动力学模拟套件EAGLE-XL。MAGPI将为宇宙中世纪的数百个星系提供精致的运动学，提供在这个关键时刻暗物质对星系影响的视图，而EAGLE-XL代表了模拟的技术前沿，并为MAGPI提供了最佳的解释框架。
