Following the first observation of gravitational waves in 2015, we have now observed around 50 signals from merging black holes and neutron stars. During your PhD, we expect to observe hundreds more signals. This PhD project involves looking for the most unique signals, such as those with highly spinning black holes exhibiting orbital precession, or binaries where the masses of the two components of the binary are very different. The project will involve obtaining a better understanding of the gravitational waves emitted by such systems; developing techniques to ensure that our searches are capable of identifying these signals buried in the detector data and ensuring that the astrophysical parameters of the system; such as the masses and spins of the black holes, are accurately measured. The search results will be used to obtain a better understanding of how these black hole and neutron star binaries are formed.

在2015年首次观测到引力波之后，我们现在已经观测到大约50个来自黑洞和中子星合并的信号。在你的博士学位期间，我们预计将观察到数百个信号。这个博士项目涉及寻找最独特的信号，例如那些具有高度旋转的黑洞表现出轨道进动的信号，或者双星中两个组成部分的质量非常不同的双星。该项目将涉及更好地了解这些系统发出的引力波;开发技术，以确保我们的搜索能够识别隐藏在探测器数据中的这些信号，并确保系统的天体物理参数，如黑洞的质量和自旋，得到准确测量。搜索结果将用于更好地了解这些黑洞和中子星星双星是如何形成的。
