will be apparent in the CMB sky. We find that slow-roll inflation produces too small bispectrum to be detected by any experiments; thus, any detection strongly constrains this class of models. We also find that the secondary bispectrum from coupling between the Sunyaev-Zel'dovich effect and the weak lensing effect, and the foreground bispectrum from extragalactic point sources, give detectable non-Gaussian signals on small angular scales.

We thus conclude that the angular bispectrum finds no significant non-Gaussian signals in the DMR data.

Bennett, Gary Hinshaw, Norman Jarosik, Lyman Page,., David. By fitting the theoretical prediction to the data for the primary bispectrum, we put a constraint on non-linearity in inflation. We compare the data with the simulated Gaussian realizations, finding no significant signal of the bispectrum on the mode-by-mode basis.

We show that high-sensitivity measurement of the CMB bispectrum and trispectrum will probe the physics of the early universe as well as the astrophysics in the low-redshift universe, independently of the CMB power spectrum.

We test Gaussianity of the, cOBE, dMR sky maps, by measuring all the modes of the angular bispectrum down to the DMR beam size.
