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

Figure 3

Effects on the matter power spectra of the PMF. (a) and (b) are for 𝑛_B=−2.0 and −1.0. The green-dashed, red-bold, and blue-dotted-dashed curves are the case of negative (𝑠_[DF]=−1), no (𝑠_[DF]=0), and positive (𝑠_[DF]=1) correlations between the matter and PMF, respectively. The black-dotted is the matter power spectrum without a PMF, and the dots with error bars show the 2df results [68].
