论文摘要
我们介绍了imrphenomxhm频域现象波形模型，用于用于准圆形非不必要黑洞二进制的灵感，合并和响应。该模型扩展了Imrphenomxas波形模型，该模型描述了主要的四极模模式$ \ ell = | m | = 2 $，对谐波$（\ ell，| m |）=（2,1），（3,3），（3,2），（4,4）$，包括$（3,2）$球形谐波的模式混合效果。对混合波形进行了校准，该杂交波形是由有效的一体模型和牛顿后振幅所描述的，用于亚抑制谐波与数值相对性波形和数值溶液与扰动Teukolsky方程的数值相对溶液的振幅相匹配，该量相匹配。 该模型的计算有效实现可作为LSC算法库套件的一部分。
We present the IMRPhenomXHM frequency domain phenomenological waveform model for the inspiral, merger and ringdown of quasi-circular non-precessing black hole binaries. The model extends the IMRPhenomXAS waveform model, which describes the dominant quadrupole modes $\ell = |m| = 2$, to the harmonics $(\ell, |m|)=(2,1), (3,3), (3,2), (4,4)$, and includes mode mixing effects for the $(3,2)$ spherical harmonic. IMRPhenomXHM is calibrated against hybrid waveforms, which match an inspiral phase described by the effective-one-body model and post-Newtonian amplitudes for the subdominant harmonics to numerical relativity waveforms and numerical solutions to the perturbative Teukolsky equation for large mass ratios up to 1000. A computationally efficient implementation of the model is available as part of the LSC Algorithm Library Suite.
