标题： Dynamics of spin-2 fields in Kerr background geometries

摘要： 我们开发了一种数值方法，用于演化旋转黑洞的扰动。 通过求解以时间的一阶形式编写的Teukolsky方程，得到解，该方程以显式展示径向特征方向的形式呈现。 我们跟踪了通用初始数据在爆发、准正则振铃和幂律尾波阶段的传播。 未来的结果可能有助于阐明黑洞角动量在黑洞合并最终阶段产生的信号中的作用。 显示英文摘要

摘要： We have developed a numerical method for evolving perturbations of rotating black holes. Solutions are obtained by integrating the Teukolsky equation written as a first-order in time, coupled system of equations, in a form that explicitly exhibits the radial characteristic directions. We follow the propagation of generic initial data through the burst, quasi-normal ringing and power-law tail phases. Future results may help to clarify the role of black hole angular momentum on signals produced during the final stages of black hole coalescence.
