论文摘要
我们报告了通过两个可比质量黑洞的合并产生的重力波形的环down阶段的非线性模式的证据。我们考虑了半圆形轨道和高能量的黑洞碰撞的黑洞二进制文件的合并。数值模拟中非线性模式的存在证实，一般性的非线性非线性很重要，必须在重力波数据分析中考虑。
We report evidence for nonlinear modes in the ringdown stage of the gravitational waveform produced by the merger of two comparable-mass black holes. We consider both the coalescence of black hole binaries in quasicircular orbits and high-energy, head-on black hole collisions. The presence of nonlinear modes in the numerical simulations confirms that general-relativistic nonlinearities are important and must be considered in gravitational-wave data analysis.
