Cosmic Strings and Their Induced Non-Gaussianities in the Cosmic Microwave Background

Figure 12

Stacking of two numerical simulations to compute the small angles CMB anisotropies induced by NG strings [197]. The dashed rectangles represent the redshift and angular extension of two numerical simulations used to evaluate (52). The first starts at last scattering and stops at while the second starts at and ends now, up to a small overlapping to ensure relaxation towards scaling.
