AI总结:

本文通过数值相对论模拟研究双黑洞并合后公共动力学视界剪切与引力辐射新闻的相关性,发现剪切包含准正则频率及 remnant 与母黑洞的质量和自旋信息,为视界相关性猜想提供证据。

摘要:

我们利用数值相对论模拟,研究准圆、无自旋双黑洞并合并合后阶段中,强场区域公共动力学视界上部分引力场与弱场区域接收到的系统引力辐射新闻之间的相关性。我们发现,与旋进阶段(Phys.Rev.Lett.125,121101)一样,旋进后期形成的公共动力学视界的剪切即使在早期时刻仍与出射引力辐射的新闻保持良好的相关性。我们通过拟合表明,剪切包含某些准正则频率以及关于 remnant 黑洞和母黑洞质量与自旋的信息,为支持视界相关性猜想在双黑洞并合中的动力学视界上成立提供了证据。

英文摘要:

We study the correlation between a part of the gravitational field at the common dynamical horizon in the strong field regime and the news of the gravitational radiation received from the system in the weak field regime, in the post-merger phase of quasi-circular, non-spinning binary black hole mergers using numerical relativity simulations. We find that, as in the inspiral phase Phys.Rev.Lett.125,121101, the shear of the common dynamical horizon formed late into the inspiral continues to be well correlated with the news of the outgoing gravitational radiation even at early times. We show by fitting that the shear contains certain quasi-normal frequencies and information about the masses and spins of the remnant and the parent black holes, providing evidence to support the horizon correlation conjecture holds for dynamical horizons in binary black hole mergers.
