Primordial Magnetic Field Effects on the CMB and Large-Scale Structure
Figure 9
Probability distributions and contours of 1 and 2 confidence limits for the standard cosmological parameters as a function of the PMF field strength and power law index . Orange contours show 1 (68%) confidence limits, and yellow contours show 2 (95%) confidence limits. Blue curves in the left and bottom of the figure show the probability distributions of each parameter. Note the existence of a maximum in the probability distributions for and . The standard cosmological parameters do not have a degeneracy with the PMF parameters because they are mainly constrained by the observed CMB data for (up to the 2nd peak), while the PMF is mainly influenced by the power on smaller angular scales and higher multipoles, .
