标题： Transfer matrices for magnetized CMB anisotropies

摘要： 大尺度磁场可以影响标量宇宙扰动，其演化在共形牛顿规范下描述，并且在紧密耦合近似内进行计算。 物质辐射平等之后（且在解耦之前）存在的磁化曲率扰动可以通过适当的转移矩阵来计算，从而对萨克斯-沃尔夫平台进行一般估计。 从宇宙微波背景初始条件应该是（主要）绝热的观测出发，可以限制磁场强度的贡献。 显示英文摘要

摘要： Large-scale magnetic fields can affect scalar cosmological perturbations whose evolution is described in the conformally Newtonian gauge and within the tight coupling approximation. The magnetized curvature perturbations present after matter radiation equality (and prior to decoupling) are computed in terms of an appropriate transfer matrix allowing a general estimate of the Sachs-Wolfe plateau. From the observation that CMB initial conditions should be (predominantly) adiabatic, the contribution of the magnetic field intensity can be constrained.
