Gravitationally-lensed gravitational waves

我加入了一个研究小组，他们希望首次探测到引力透镜引力波。如果成功的话，这将是第一次一个观测包含了爱因斯坦的两个广义相对论预测。我的研究从使用光学数据来寻找星系团强透镜开始。这将包括涉及LSST（大型综合巡天望远镜）的工作，为2022年开始的巡天操作做好准备。定位这些星系团是探测引力透镜波的关键一步。随着项目的发展，可能会出现更多相关的研究领域，例如星系团建模。透镜放大了来自物体的信号，如果它们没有透镜，就不会被观察到。这对引力波透镜特别重要，因为它们来自太远的源，如果没有透镜的帮助，就无法探测到-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.
