论文摘要
我们分析了从稳定的地球化学中移动的巨大颗粒发出的光子的频移，这些颗粒围绕具有非线性电动力学的黑洞稳定。当爱因斯坦重力与非线性电动力学耦合时，光子的运动通过有效度量进行了修饰。光子的运动学偏移是通过磁性和电因子和非线性电动力学之间差异的。作为例证，我们介绍了具有非线性电动力学，两个磁性黑洞和两个电动黑洞的黑洞的光子的频移，Bardeen和Bronnikov黑孔，用于磁性电荷以及出生的Infeld和Dymnikova黑洞，用于电荷。将这些频移与它们的线性电磁对应物进行了比较。
We analyzed the frequency shifts of photons emitted from massive particles that move in stable geodesics around black holes with non-linear electrodynamics. The motion of the photon is modified by an effective metric when the Einstein gravity is coupled with non-linear electrodynamics. The kinematic shifts for photons are modified by the magnetic and electric factors that make the difference between the linear and non-linear electrodynamics. As an illustration, we present the frequency shifts of the photons for black holes with non-linear electrodynamics, two magnetic black holes, and two electric black holes, the Bardeen and Bronnikov black holes for the magnetic charge and the Born-Infeld and Dymnikova black holes for electric charge. These frequency shifts are compared with their linear electromagnetic counterpart.
