论文摘要

在这项工作中,我们提出了Imrphenomtp,这是一个主域的现象学模型,用于主导$ L = 2 $,$ M = | 2 | $合并的黑洞二进制系统及其扩展,以描述“扭曲”近似值中的一般预系统系统。基本的非潜在模型被校准为SXS协作的数值相对性模拟的新版本,其准确性与最新的非潜在主导模式相媲美,即Imrphenomx和Seobnrv4。进取的扩展可以使灵活性选择共同的参考和惯性参考系统之间时间相关的旋转的欧拉角,包括单个旋转NNLO和其他模型中存在的双旋转MSA PN描述,轨道平均自旋进化方程的数值集成,用于旋转旋转方程的数值集成,对于轨道近似行为的不同选择,以及一个简单的旋转动量和一个简单的旋转态度。

In this work we present IMRPhenomTP, a time domain phenomenological model for the dominant $l=2$, $m=|2|$ modes of coalescing black hole binary systems and its extension to describe general precessing systems within the "twisting up" approximation. The underlying non-precessing model is calibrated to the new release of Numerical Relativity simulations of the SXS Collaboration and its accuracy is comparable to the state-of-the-art non-precessing dominant mode models as IMRPhenomX and SEOBNRv4. The precessing extension allows for flexibility choosing the Euler angles of the time-dependent rotation between the co-precessing and the inertial reference systems, including the single spin NNLO and the double spin MSA PN descriptions present in other models, numerical integration of the orbit averaged spin evolution equations, different choices for the evolution of the orbital angular momentum norm and a simple approximation to the ringdown behaviour.
