论文摘要
我们研究了吞咽一个或多个全球单极管的黑洞，轴向重力波的短高斯脉冲散射。我们展示了黑洞对撞击脉冲的响应如何取决于黑洞已吞噬的单孔的数量以及模型的对称断裂量表，从而导致了单孔。我们确定了相应的准模式，这些模式会因撞击脉冲而激发，并印在黑洞对脉冲的响应中。预计此类模式还会出现在其他各种动力学过程中，例如二进制黑洞合并的环down阶段，以防至少一个二进制的伴随黑洞之一吞噬了一个或多个全球单调。
We study scattering of short Gaussian pulses of axial gravitational waves by a black hole that has swallowed one or more global monopoles. We show how the response of the black hole to the impinging pulses depends both on the number of monopoles the black hole has swallowed and on the symmetry breaking scale of the model which gave rise to the monopoles. We determine the corresponding quasinormal modes that get excited by the impinging pulses and that get imprinted in the black hole's response to the pulses. Such modes are also expected to show up in various other dynamical processes such as the ringdown phase of a binary black hole merger in case at least one of the companion black holes of the binary has swallowed one or more global monopoles.
