论文摘要
我们介绍了两个相等的质量，在双曲线样轨道上的散射角$χ$χ$χ$χ$χ$χ$的新数值相对论计算。我们以先前的工作为基础，首次考虑旋转黑洞，同样的旋转与轨道角动量对齐或抗静脉。我们详细介绍用于计算$χ$的数值技术。在估计计算数量的错误不确定性时要格外小心。将数值与使用新的，最先进的有效的一个身体模型获得的分析预测进行了比较，该模型有效，有效，该模型在非替代，保守的部门中纳入了牛顿后的分析信息，最高为5pn，并且还通过数值相对性模拟了Quasi-Circular Circular Cobles Cocular Cocular Cobless Blacksed Blacksed Blacksed Blacksed Blacksed Blacksed Blacksed Blacksed Blacksess Blacksed Blacksess Backessed Blacksed Black bolling Blackessed Blacksed Black holes。我们的结果表明，应进一步改进分析模型的自旋部门，以与最相对论的旋转配置达到令人满意的一致性。
We present new Numerical Relativity calculations of the scattering angle $χ$ between two, equal-mass, black holes on hyperbolic-like orbits. We build upon previous work considering, for the first time, spinning black holes, with equal spins either aligned or antialigned with the orbital angular momentum. We detail the numerical techniques used in the computation of $χ$. Special care is taken in estimating error uncertainties on the quantities computed. The numerical values are compared with analytical predictions obtained using a new, state-of-the-art, effective one body model valid on generic orbits that incorporates post-Newtonian analytic information up to 5PN in the nonspinning, conservative sector and that has been additionally informed by Numerical Relativity simulations of quasi-circular coalescing black hole binaries. Our results indicate that the spin sector of the analytic model should be improved further in order to achieve satisfactory consistency with the most relativistic spinning configurations.
