论文摘要
最近，已经表明，通过泛音，使用纯线性理论对二进制黑洞系统无穷大的合并后重力波形进行了良好的模型。但是，鉴于二进制黑洞合并有望是高度非线性的，这些非线性在哪里，不会使它成为无穷大？我们可以看到数值相对性二进制黑洞合并的强场地中非线性的数量，以便开始回答这个问题。
Recently, it has been shown that with the inclusion of overtones, the post-merger gravitational waveform at infinity of a binary black hole system is well-modelled using pure linear theory. However, given that a binary black hole merger is expected to be highly non-linear, where do these non-linearities, which do not make it out to infinity, go? We visualize quantities measuring non-linearity in the strong-field region of a numerical relativity binary black hole merger in order to begin to answer this question.
