Revealing the Unseen Universe with Gravitational Lensing

该项目将分析来自哈勃太空望远镜的新的澳大利亚领导的观测结果，这些观测结果表明，光在重力作用下围绕着大质量星系弯曲。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。这种分析将为我们提供早期星系演化的高度放大视图，揭示否则无法看到的物理细节。它还将使我们能够对不可见暗物质的性质进行限制，从而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膨胀，测试看不见的暗能量是否在及时演变。哈勃的样本要大得多，是对以前工作的重大进步，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.
