Topics in gravitational wave cosmology

最近发现的来自双星黑洞和中子星的引力波，为解决宇宙中一些最大的奥秘打开了新的可能性：最高尺度的自然暗能量、暗物质和引力，即量子引力。该项目将探索使用引力波对引力基本理论(如弦理论)进行测试的可能性。更具体地说，该项目旨在解决以下问题：在未来的干涉仪上能否检测到额外维度的存在？如果不能，我们可以从这些理论中学到什么？这些理论中的引力记忆效应是否经过修正，并使用引力波进行探测？这些理论中有没有预言过的奇异物体，这些物体在引力波的产生和演化中有没有体现出来？该项目旨在使用分析、数值和计算工具来解决这些问题，并将重点放在爱因斯坦望远镜的科学以及其他(当前和未来的)引力波实验上。

The recent discovery of gravitational waves from binary black holes, and neutron stars, has open up new possibilities to solve some of the greatest mysteries of the universe: the nature dark energy, dark matter, and gravity at the highest scales, namely, quantum gravity. The project will explore possible tests of fundamental theories of gravity, such as string theory, using gravitational waves. More concretely, the project aims at addressing questions such as the following:Can the presence of additional dimensions be detected at future interferometers and if not, what can we learn about these theories? Are gravitational memory effects in these theories modified, and be detected using gravitational waves? Are there any exotic objects predicted in these theories, and do these show up in the gravitational waves' production and evolution? The project aims at using analytical, as well as numerical and computational tools to address these questions and it will have some focus on the science of the Einstein Telescope, as well as other (current and future) gravitational wave experiments.
