This project proposes a multi-wavelength study of optically elusive, dark matter dominated satellite galaxies around the Milky Way. These ultra-faint stellar systems, the first to be discovered in the Southern Hemisphere are the building blocks of our Milky Way and are prime laboratories to assess the stellar and dark matter properties of the most extreme galaxies known. The results are expected to provide crucial insights into the nature of dark matter and the cosmic formation of chemical elements, thereby strengthening Australia's research capacity in one of the most exciting frontiers of astrophysics research.

该项目计划对银河系周围以暗物质为主的光学难以捉摸的卫星星系进行多波长研究。这些超暗的恒星系统是在南半球发现的第一个恒星系统，是我们银河系的基石，是评估已知最极端星系的恒星和暗物质性质的主要实验室。预计这些结果将对暗物质的性质和化学元素的宇宙形成提供至关重要的见解，从而加强澳大利亚在天体物理研究最令人兴奋的前沿之一的研究能力。
