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

Figure 21

Large-scale contributions to the galaxy bispectrum due to primordial non-Gaussianity of the local (a) and equilateral (b) type described as one-loop corrections assuming a local bias prescription. Thin lines correspond to the contributions for Gaussian initial conditions, from the study by Sefusatti in [171]; see the reference for further details.
