TEOBResumS：多极二元黑洞波形中一致的准圆修正和后绝热近似的评估
TEOBResumS: assessment of consistent next-to-quasicircular corrections and post-adiabatic approximation in multipolar binary black holes waveforms
摘要：
在引力波天文学中，使用有效单体（EOB）波形分析黑洞双星需要可靠的模型和快速的产生时间。实现忠实性的一个关键方面是包括数值相对论（NR）通知下准圆修正（NQC），依赖于径向动量，波形和辐射反应。加速波形生成的鲁棒方法是后绝热迭代以近似EOB哈密顿方程的解。在这项工作中，我们评估的性能相结合的后绝热方法产生多极引力波的快速NQC处方。所概述的方法允许在波形和辐射反应中对NQC进行一致的处理，不需要迭代程序来实现高忠实性，并且可以有效地用于参数估计。与611 NR模拟相比，对于总质量$10M_\odot\leq M \leq 200M_\odot$并使用Advanded LIGO噪声，该模型具有远低于$0.01$的EOB/NR不忠实性，其中78.5%的情况低于$0.001$。我们将该模型应用于GW 150914的参数估计，探索新的NQC和更高模式的影响，直到$\ell=m=8$。
英文摘要：
The use of effective-one-body (EOB) waveforms for black hole binaries analysis in gravitational-wave astronomy requires faithful models and fast generation times. A key aspect to achieve faithfulness is the inclusion of numerical-relativity (NR) informed next-to-quasicircular corrections(NQC), dependent on the radial momentum, to the waveform and radiation reaction. A robust method to speed up the waveform generation is the post-adiabatic iteration to approximate the solution of the EOB Hamiltonian equations. In this work, we assess the performances of a fast NQC prescription in combination to the post-adiabatic method for generating multipolar gravitational waves. The outlined approach allows a consistent treatment of NQC in both the waveform and the radiation-reaction, does not require iterative procedures to achieve high faithfulness, and can be efficiently employed for parameter estimation. Comparing to 611 NR simulations, for total mass $10M_\odot\leq M \leq 200M_\odot$ and using the Advanded LIGO noise, the model has EOB/NR unfaithfulness well below $0.01$, with 78.5\% of the cases below $0.001$. We apply the model to the parameter estimation of GW150914 exploring the impact of the new NQC and of the higher modes up to $\ell=m=8$.
