In the first year, the project concerns the scattering, absorption and emission of an electromagnetic field by a rotating (Kerr) black hole. The student will use the Debye/Hertz potential approach of Cohen & Kegeles (1974), to reconstruct the Faraday tensor on a Kerr black hole background by acting on a single complex scalar quantity with differential operators. The complex scalar is governed by a second-order PDE that is separable. By constructing a sum over the modes, the student will examine aspects such as planar wave scattering (via scattering cross sections); quasi-normal modes and Regge pole spectra; and electromagnetic self-force.

在第一年，该项目关注旋转（克尔）黑洞对电磁场的散射、吸收和发射。学生将使用Cohen & Kegeles（1974）的Debye/Hertz势方法，通过作用于单个带微分算子的复标量来重建Kerr黑洞背景上的法拉第张量。复标量由可分离的二阶偏微分方程控制。通过构建模式的总和，学生将研究诸如平面波散射（通过散射截面）；准正态模和Regge极谱；还有电磁力。
