大质量暗晕引力场中的电磁波
Electromagnetic waves in the gravitational field of massive dark halos
摘要：
分析了旋转暗物质云中平面电磁波在引力场中的传播。根据云的质量密度和角速度，得到了光的偏转、吸收和偏振面旋转的封闭式公式。结果表明，对于轴对称构型，这些公式可以大大简化。作为一个例子，形式主义被应用到旋转的大质量云描述的普卢默潜力。
英文摘要：
The propagation of plane electromagnetic waves in the gravitational field inside a rotating cloud of dark matter is analyzed. Formulas for the deflection and absorption of light, and the rotation of the polarization plane are obtained in closed form in terms of the mass density and the angular velocity of the cloud. It is shown that the formulas can be considerably simplified for axisymmetric configurations. As an example, the formalism is applied to a rotating massive cloud described by a Plummer potential.
