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.

这个项目将分析由哈勃太空望远镜新观测到的由澳大利亚领导的关于光线在重力作用下绕着大质量星系弯曲的观测。为了分析这些图像，我们必须开发先进的物理模型和统计技术。这一分析将为我们提供早期星系演化的高度放大的视角，揭示否则不可能看到的物理细节。它还将使我们能够通过探测热暗物质信号来限制不可见暗物质的性质，并使我们能够探测宇宙的膨胀，测试看不见的暗能量是否在随时间演变。哈勃的样本比以前的工作大得多，是一个重大进步，使这些领域的科学突破成为可能。
