Primordial Non-Gaussianity in the Large-Scale Structure of the Universe

Figure 3

Reduced matter bispectrum 𝑄₃ as a function of the angle 𝜃 between 𝐤₁ and 𝐤₂ for a fixed 𝑘₁=0.094hMpc⁻¹ and 𝑘₂=1.5𝑘₁. The panels show ratios between the non-Gaussian and Gaussian 𝑄₃ for 𝑓^loc_NL=+100 (top) and −100 (bottom). Dashed lines correspond to tree-level PT while continuous line indicates the 1-loop PT prediction.
