Revealing the Unseen Universe with Gravitational Lensing

这个项目将分析由澳大利亚领导的哈勃太空望远镜观测到的光在大质量星系周围被引力弯曲的新观测结果。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。这项分析将为我们提供早期星系演化的高度放大视图，揭示否则不可能看到的物理细节。它还将允许我们对不可见暗物质的本质施加限制，从而有可能探测到温暖暗物质的特征，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及时演化。哈勃望远镜的样本要大得多，是以往工作的重大进步，并使这些领域的科学突破成为可能。

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.
