This project aims to discover clues to the nature of dark matter buried in small-scale structures. Although observational probes reliably constrain these systems, theoretical progress is hampered by difficulties disentangling the complex baryonic physics from the micro-physics of the dark matter particle in shaping the structure of low-mass galaxies. The project will tackle this problem using sophisticated numerical simulations which separate these effects, allowing them to be isolated. The results are expected to show how low-mass galaxy formed, and to have important implications for modelling dark matter annihilation and for interpreting data from forthcoming surveys.

该项目旨在发现隐藏在小尺度结构中的暗物质性质的线索。虽然观测探测器可靠地限制了这些系统，但在塑造低质量星系结构时，难以将复杂的重子物理学与暗物质粒子的微观物理学分开，这阻碍了理论的进展。该项目将使用复杂的数值模拟来解决这个问题，这些模拟将这些影响分开，使它们能够被隔离。预计这些结果将显示低质量星系是如何形成的，并对暗物质湮灭建模和解释即将到来的调查数据具有重要意义。
