论文摘要
我们使用分析模型波形构建混合二进制黑洞的合并波形，用于早期的灵感相和数值相对性波形，以使后期灵感与合并和后置合并阶段。为了杂交分析和数值波形，我们首先执行3维旋转，以使与两个波形相关的瞬时轨道平面在某些基准频率下与两个波形相关，然后我们找到合适的阶段和时间翻译，以最大程度地翻译杂交间隔中两个波形的重叠。我们讨论了该程序在Ligo-Virgo-Kagra观察的背景下构建的混合体的准确性和局限性。我们的目标是杂交波形以进行更通用的进攻性二进制文件，并构建更长的波形，这些波形足够准确地对于即将进行的LIGO观察的参数估计技术。
We construct hybrid binary black holes merger waveforms using analytical model waveforms for the early inspiral phase and numerical relativity waveforms for late inspiral to merger and post merger phases. To hybridize analytical and numerical waveforms, we first perform a 3-dimensional rotation to align the instantaneous orbital planes associated with the two waveforms at some fiducial frequency, we then find appropriate phase and time translations that maximize the overlap of the two waveforms in a hybridization interval. We discuss the accuracy and limitations for hybrids constructed by this procedure in the context of LIGO-Virgo-KAGRA observations. Our goal is to hybridize waveforms for more generic precessing binaries and construct longer waveforms that are sufficiently accurate for the parameter estimation techniques for upcoming LIGO observations.
