In this paper we present theoretical model calculations involving Monte Carlo computer simulations of Compton scattering and electron-positron (e-e+) pair production processes in the ergosphere of a supermassive rotating black hole. Particles from an accretion disk surrounding the rotating black hole fall into the ergosphere and are scattered by particles that are confined in equatorial and nonequatorial orbits. The energy-momentum vectors are calculated for the scattered escaping particles. Particles escape with energies of about 3 GeV or greater. Importantly, these model calculations show that the Lense-Thirring effect, that is, the dragging of local inertial frames into rotation, inside the ergosphere, caused by the angular momentum of the rotating black hole, results in a gravitomagnetic force being exerted on the scattered escaping particles. Effects of this force on the Penrose scattered particles are analyzed and discussed.
在本文中,我们展示了理论模型计算,其中涉及对超大质量旋转黑洞能层中的康普顿散射以及电子 - 正电子(e - e⁺)对产生过程的蒙特卡罗计算机模拟。来自围绕旋转黑洞的吸积盘的粒子落入能层,并被限制在赤道和非赤道轨道上的粒子散射。计算了散射后逃逸粒子的能量 - 动量矢量。粒子以约3 GeV或更高的能量逃逸。重要的是,这些模型计算表明,能层内部由旋转黑洞的角动量引起的局部惯性系拖曳旋转的兰斯 - 蒂林效应,会导致对散射后逃逸的粒子施加一个引力磁力。分析并讨论了该力对彭罗斯散射粒子的影响。
