Primordial Non-Gaussianity in the Large-Scale Structure of the Universe
Figure 1
Skewness of the smoothed density field in unit of for the local, equilateral, and folded bispectrum shapes. The skewness for the equilateral and folded templates is a factor of 3 smaller than in the local model. In any case, this implies that on the scales probed by the large-scale structure for realistic values of the nonlinear coupling parameter, . The shaded regions approximately indicate the range of scales probed by various LSS tracers. For the galaxy power spectrum and bispectrum, the upper limit sensitively depends upon the surveyed volume.
