Gravitational wave astrophysics with binary black holes

2015年，在爱因斯坦的广义相对论预言引力波存在的100年后，先进的LIGO探测到有史以来第一个来自双黑洞合并的引力波信号。虽然所有的双黑洞观测都是针对稳定的双系统中的黑洞，但我们也期望从其他来源（如黑洞遭遇）发射引力波。黑洞在密集的天体物理环境中移动，比如球状星团，可能会分散彼此的引力势，或者在合并之前被捕获在一个固定的轨道上。目的和目标：本项目将通过分析单个黑洞合并产生的引力波信号，以及研究高级LIGO探测器观测到的双黑洞群体的整体特性及其升级，探索双黑洞天体物理学。研究方法的创新：本项目将采用先进的贝叶斯推理技术，如分层建模和模型选择。它还将探索机器学习在探测和天体物理学中的应用。

In 2015, one hundred years after Einstein's General Theory of Relativity predicted the existence of gravitational waves, Advanced LIGO detected the first ever gravitational wave signal from binary black hole mergers. While all binary black hole observations made since have been for black holes in stable binary systems, we also expect gravitational wave emissions from other sources such black hole encounters. Black holes moving through dense astrophysical environments such as globular clusters, can scatter off each other's gravitational potential or become captured in a bound orbits before merging. Aims and objectives: This project will explore binary black hole astrophysics through the analysis of the gravitational wave signals from individual black hole mergers as well as studying the overall properties of the binary black hole population observed by the Advanced LIGO detectors and its upgradeNovelty of the research methodology: The project will employ advanced Bayesian inference techniques such as hierarchical modelling and model selection. It will also explore the use of machine learning for detection and astrophysics.
