This project will analyse new Australian led observations from the Hubble Space Telescope of light being bent around massive galaxies by gravity. To analyse these images we must develop advanced physical models and statistical techniques. This analysis will give us highly magnified views of early galaxy evolution revealing physical details otherwise impossible to see. It will also allow us to put constraints on the nature of invisible dark matter with the possibility of detecting warm dark matter signatures and enable us to probe the expansion of the Universe, testing whether the unseen dark energy is evolving in time. The Hubble sample is much larger and a major advance on previous work, and enables breakthrough science in these areas.

该项目将分析来自哈勃太空望远镜的新澳大利亚LED观察结果，这些望远镜在重力上弯曲了大型星系。要分析这些图像，我们必须开发高级物理模型和统计技术。该分析将使我们对早期星系进化的高度放大观点，揭示了物理细节，否则看不到。它还将使我们能够对看不见的暗物质的性质进行限制，并有可能检测到温暖的暗物质特征并使我们能够探测宇宙的扩张，从而测试未看到的暗能量是否在及时发展。哈勃样本要大得多，并且在以前的工作上是一个重要的进步，并在这些领域实现了突破性的科学。
