标题： Testing gravitational waveforms in full General Relativity

摘要： 我们对最先进的波形模型进行了全面分析，重点在于它们关于踢速度和推断的引力波记忆的预测。 在我们的研究中，我们使用能量动量守恒定律来评估波形模型的准确性，这些定律是在完整的非线性广义相对论框架中推导得出的。 数值准确性评估针对属于\textit{结束}、\textit{现象}和\textit{代理}家族的模型，涵盖了进动和非进动情况。 我们分析了这些模型彼此之间以及与数值相对论波形之间的偏差。 我们的分析揭示了统计上显著的偏差，我们将这些偏差归因于次主导模式建模的不准确性以及所选模型中的固有系统误差。 我们通过关于计算出的踢速度和推断的记忆中谐波模式混合的分析考虑来证实我们的发现。 显示英文摘要

摘要： We perform a comprehensive analysis of state-of-the-art waveform models, focusing on their predictions concerning kick velocity and inferred gravitational wave memory. In our investigation we assess the accuracy of waveform models using energy-momentum balance laws, which were derived in the framework of full, non-linear General Relativity. The numerical accuracy assessment is performed for precessing as well as non-precessing scenarios for models belonging to the \textit{EOB}, \textit{Phenom}, and \textit{Surrogate} families. We analyze the deviations of these models from each other and from Numerical Relativity waveforms. Our analysis reveals statistically significant deviations, which we trace back to inaccuracies in modelling subdominant modes and inherent systematic errors in the chosen models. We corroborate our findings through analytical considerations regarding the mixing of harmonic modes in the computed kick velocities and inferred memories.
