Gravitational wave astrophysics with binary black holes

2015年，在爱因斯坦的广义相对论预测引力波存在的一百年后，Advanced LIGO探测到了有史以来第一个来自双黑洞合并的引力波信号。虽然所有的二元黑洞观测都是针对稳定的二元系统中的黑洞，但我们也期待来自其他来源的引力波发射，例如黑洞遭遇。黑洞在密集的天体物理环境中运动，如球状星团，可以分散彼此的引力势，或者在合并之前被捕获在一个束缚的轨道上。宗旨和目标：该项目将通过分析单个黑洞合并的引力波信号以及研究高级LIGO探测器观察到的二元黑洞群体的整体性质及其研究方法的新颖性来探索二元黑洞天体物理学：该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.
