Gravitationally-lensed gravitational waves

我加入了一个研究团队，他们希望首次探测到引力透镜引力波。如果成功，这将是第一次有一个观测包含了爱因斯坦关于广义相对论的两个预言。我的研究始于使用光学数据来寻找星系团的强透镜。这将包括与大型天气观测望远镜(LSST)有关的工作，为2022年开始的调查业务做好准备。定位这些星团是探测透镜状引力波的关键一步。随着项目的发展，可能会出现更多相关的研究领域，例如对星系团进行建模。透镜放大了来自物体的信号，如果没有透镜，这些物体是看不到的。这与透镜引力波尤其相关，因为它们将来自距离太远而无法在没有透镜帮助的情况下被探测到的源--有效地提高了引力波探测器的灵敏度。

I am joining a team of researchers that are hoping to make the first detection of a gravitationally-lensed gravitational wave. If successful, this will be the first time that a single observation has encompassed two of Einstein's predictions of general relativity. My research begins by using optical data to find galaxy cluster strong lenses. This is to include work involving the LSST (Large Synoptic Survey Telescope), in readiness for the beginning of its survey operations in 2022. Locating these clusters is a key step toward being able to detect lensed gravitational waves. As the project develops, further related areas of research may arise, such as modelling galaxy clusters. Lensing magnifies the signals from objects which, if they were not lensed, would not be observable. This is particularly relevant for lensed gravitational waves, because they will come from sources too distant to be detected without the help of lensing - effectively increasing the sensitivity of gravitational wave detectors.
