Primordial Magnetic Field Effects on the CMB and Large-Scale Structure

Figure 1

Comparison of CMB temperature fluctuations from the scalar mode with (red thick curve) and without (thin dashed curve) terms of 𝒪(𝜏²) from the matter contributions to the scale factor. For this plot, we have set 𝐵_𝜆=1.0 nG and 𝑛_B=−2.9.
