| « The CMB bispectrum on large angular scales » |
|
F. Vernizzi |
| I will discuss the calculation of the CMB anisotropies on large angular scales, extending at second order in the perturbations the classic Sachs-Wolfe result delta T/T = 1/3 Phi. I will then compute the CMB bispectrum, i.e. the 3-point function, and its shape dependence. This will be compared to the estimators for the non-Gaussianities that will be tightly constrained by the Planck satellite. |
