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

Figure 22

Measurements of a set of triangular configurations of the halo bispectrum in N-body simulations with local non-Gaussian initial conditions, as a function of the non-Gaussian parameter . Large values of the parameter correspond to more squeezed configurations. In the upper panels, the dependence of the halo bispectrum on is evident, from the study by Nishimichi et al. in [213].
