磁场对末次电子-光子散射的贡献
Magnetic field contribution to the last electron-photon scattering
摘要：
当宇宙微波光子在物质和辐射退耦之前散射电子时，磁场确实对斯托克斯矩阵以及亮度扰动的输运方程的标量、矢量和张量分量有贡献。本文第一次考虑了任意方向的磁场的贡献，并在标量、矢量和张量几何模式的情况下，对磁化电子-光子散射作了一般性的讨论。本文讨论了在不同的磁场方向和不同的光子方向下残余矢量和残余引力子的传播。源项的输运方程中存在的相对论波动的几何形状也明确平均的磁场的方向和一个一致的帐户的小规模和大规模的磁场的问题进行了简要概述。
英文摘要：
When the cosmic microwave photons scatter electrons just prior to the decoupling of matter and radiation, magnetic fields do contribute to the Stokes matrix as well as to the scalar, vector and tensor components of the transport equations for the brightness perturbations. The magnetized electron-photon scattering is hereby discussed in general terms by including, for the first time, the contribution of magnetic fields with arbitrary direction and in the presence of the scalar, vector and tensor modes of the geometry. The propagation of relic vectors and relic gravitons is discussed for a varying magnetic field orientation and for different photon directions. The source terms of the transport equations in the presence of the relativistic fluctuations of the geometry are also explicitly averaged over the magnetic field orientations and the problem of a consistent account of the small-scale and large-scale magnetic field is briefly outlined.
