Primordial Non-Gaussianity and Bispectrum Measurements in the Cosmic Microwave Background and Large-Scale Structure

Figure 8

The reduced CMB bispectra for several non-Gaussian models, including ((a), (b) and (c)) equilateral, local, and flattened models and ((d), (e), and (f)) warm, feature, cosmic string models (see main text). All five primordial models are normalised relative to the constant solution (49) and are taken from the study by Fergusson and Shellard in [9]. The analytic cosmic string bispectrum (64) is multiplied by and is taken from the study by Regan and Shellard in [59].
