This project aims to reveal the dark matter that envelops the Milky Way, deconstructing its mass through observations of cannibalised smaller galaxies. Uniting ground- and space-based observations, this project expects to uncover the detailed size and shape of the Galaxy's dark matter halo through dynamical modelling of dwarf galaxies as they are disrupted by Galactic tidal forces. As well as determining this dominant mass, the expected outcomes of this project include a unique snapshot of the evolution of our Milky Way. Leveraging major international collaborations and producing high-impact scientific results, this project will address the primal question of origins, yielding important societal and cultural benefits.

该项目旨在揭示包围银河系的暗物质，通过观察蚕食较小的星系来解构其质量。该项目结合地面和太空观测，预计通过对矮星系受到银河潮汐力扰乱的动力学建模，揭示银河系暗物质晕的详细大小和形状。除了确定这个主导质量之外，该项目的预期成果还包括我们银河系演化的独特快照。该项目将利用重大国际合作并产生高影响力的科学成果，解决起源的基本问题，产生重要的社会和文化效益。
