标题： Post-Newtonian templates for gravitational waves from compact binary inspirals

摘要： 为了实现对来自致密双星系统的引力波观测的检测并最大化物理输出，提供准确的波形模型至关重要。 本工作旨在为非专家提供关于在致密双星并合引力波数据分析中使用的（ inspiral ）波形的概述。 我们首先在简单的牛顿轨道动力学和线性化引力理论框架内，提供引力辐射物理的基本要素，并描述应用于双星系统的绝热近似：这是在实践中构建理论引力波形的关键要素。 接下来，我们介绍了广义相对论的后牛顿近似下的引力波形，并强调了缓慢演化、自旋、非进动、准圆轨道的双黑洞合并的 inspiral 波形的基本输入，即后牛顿能量、通量以及（吸收修正后的）平衡方程。 随后，以时域和频域两种方式呈现后牛顿 inspiral 模板。 最后，包括合并和后续的回音阶段，我们简要调查目前在 LSC 算法库仿真中实现的两种完整的双星合并波形模型家族：有效单体方法和现象学频域模型。 显示英文摘要

摘要： To enable detection and maximise the physics output of gravitational wave observations from compact binary systems, it is crucial the availability of accurate waveform models. The present work aims at giving an overview for non-experts of the (inspiral) waveforms used in the gravitational wave data analysis for compact binary coalescence. We first provide the essential elements of gravitational radiation physics within a simple Newtonian orbital dynamics and the linearized gravity theory, describing the adiabatic approximation applied to binary systems: the key element to construct the theoretical gravitational waveforms in practice. We next lay out the gravitational waveforms in the post-Newtonian approximation to General Relativity, and highlight the basic input for the inspiral waveform of the slowly evolving, spinning, nonprecessing, quasicircular binary black holes, namely, post-Newtonian energy, fluxes and the (absorption-corrected) balance equation. The post-Newtonian inspiral templates are then presented both in the time and frequency domain. Finally, including the merger and subsequent ringdown phase, we briefly survey the two families of the full waveform models of compact binary mergers currently implemented in LSC Algorithm Library Simulation: the effective-one-body approach and the phenomenological frequency domain model.
