CMB bispectrum, trispectrum, non-Gaussianity, and the Cramer-Rao bound
Minimum-variance estimators for the parameter fnl that quantifies local-model non-Gaussianity can be constructed from the cosmic microwave background (CMB) bispectrum (three-point function) and also from the trispectrum (four-point function). Some have suggested that a comparison between the estimates for the values of fnl from the bispectrum and trispectrum allow a consistency test for the mod...
متن کاملThe Best Unbiased Estimator for the Cmb Angular Bispectrum
While the statistical properties of the CMB anisotropies are a powerful means to discriminate amongst the possible cosmological scenarios, actually measuring non-Gaussianity in the data is a very difficult task1. The typically small signal should be compared to the noise and the key quantity is the signal to noise ratio. The noise creeps into the dataset through instrumental errors, foregrounds...
متن کاملCMB lensing extraction and primordial non-Gaussianity
The next generation of CMB experiments should get a better handle on cosmological parameters by mapping the weak lensing deflection field, which is separable from primary anisotropies thanks to the non-Gaussianity induced by lensing. However, the generation of perturbations in the Early Universe also produces a level of non-Gaussianity which is known to be small, but can contribute to the aniso...
متن کاملEvidence for non-Gaussianity in the CMB
In a recent Letter we have shown how COBE-DMRmaps may be used to disprove Gaussianity at a high confidence level. In this report we digress on a few issues closely related to this Letter. We present the general formalism for surveying non-Gaussianity employed. We present a few more tests for systematics. We wonder about the theoretical implications of our result.
متن کاملTesting Primordial Non-Gaussianity in CMB Anisotropies
Recent second-order perturbation computations have provided an accurate prediction for the primordial gravitational potential, Φ(x), in scenarios in which cosmological perturbations are generated either during or after inflation. This enables us to make realistic predictions for a nonGaussian part of Φ(x), which is generically written in momentum space as a double convolution of its Gaussian pa...
