Abstract

This review provides a conceptual and technical survey of methods for parameter estimation of gravitational-wave signals in ground-based interferometers such as Laser Interferometer Gravitational-Wave Observatory (LIGO) and Virgo. We introduce the framework of Bayesian inference and provide an overview of models for the generation and detection of gravitational waves from compact binary mergers, focusing on the essential features that are observable in the signals. Within the traditional likelihood-based paradigm, we describe various approaches for enhancing the efficiency and robustness of parameter inference. This includes techniques for accelerating likelihood evaluations, such as heterodyne/relative binning, reduced-order quadrature, multibanding, and interpolation. We also cover methods to simplify the analysis to improve convergence, via reparameterization, importance sampling, and marginalization. We end with a discussion of recent developments in the application of likelihood-free (simulation-based) inference methods to gravitational-wave data analysis.

从引力波信号推断双星属性

这篇综述从概念和技术角度对激光干涉引力波天文台（LIGO）和室女座等地基干涉仪的引力波信号参数估计方法进行了研究。我们介绍了贝叶斯推理框架，并概述了紧凑型双星合并产生和探测引力波的模型，重点是信号中可观测到的基本特征。在传统的基于似然法的范式中，我们介绍了提高参数推断效率和稳健性的各种方法。这包括加速似然评估的技术，如异频/相对分档、降阶正交、多频带和插值。我们还介绍了通过重参数化、重要性采样和边际化来简化分析以提高收敛性的方法。最后，我们将讨论无似然（基于模拟）推理方法在引力波数据分析中应用的最新进展。
