标题： Accurate waveform models for gravitational-wave astrophysics: synergetic approaches from analytical relativity

摘要： 引力波（GW）天体物理学是一个蓬勃发展的领域。 自2015年9月14日首次探测到双黑洞的引力波以来，LIGO-Virgo合作组织已报告了多个致密天体双星系统。 这些事件包含了从理解黑洞和中子星的形成、中子星的组成、宇宙的膨胀，到在高度动态的强场区域测试广义相对论的天体物理和宇宙学信息。 GW天体物理学的目标是尽可能准确地提取这些信息。 然而，这只有在用于探测和分析GW的工具和技术足够先进时才有可能实现。 GW搜索的关键方面是波形模型，这些模型概括了在一定参数集下我们对引力辐射的最佳预测，并需要与数据进行交叉相关以提取GW信号。 波形必须非常精确，以避免在数据中遗漏重要的物理现象，这可能是回答GW天体物理学基本问题的关键。 当前LIGO-Virgo探测器的持续改进、下一代地面探测器如爱因斯坦望远镜或宇宙探索者的发展，以及激光干涉空间天线（LISA）的发展，都要求精确的波形模型。 [简写。] 显示英文摘要

摘要： Gravitational-wave (GW) astrophysics is a field in full blossom. Since the landmark detection of GWs from a binary black hole on September 14th 2015, several compact-object binaries have been reported by the LIGO-Virgo collaboration. Such events carry astrophysical and cosmological information ranging from an understanding of how black holes and neutron stars are formed, what neutron stars are composed of, how the Universe expands, and allow testing general relativity in the highly-dynamical strong-field regime. It is the goal of GW astrophysics to extract such information as accurately as possible. Yet, this is only possible if the tools and technology used to detect and analyze GWs are advanced enough. A key aspect of GW searches are waveform models, which encapsulate our best predictions for the gravitational radiation under a certain set of parameters, and that need to be cross-correlated with data to extract GW signals. Waveforms must be very accurate to avoid missing important physics in the data, which might be the key to answer the fundamental questions of GW astrophysics. The continuous improvements of the current LIGO-Virgo detectors, the development of next-generation ground-based detectors such as the Einstein Telescope or the Cosmic Explorer, as well as the development of the Laser Interferometer Space Antenna (LISA), demand accurate waveform models.
