Name: Cyril PITROU Institution: Institute of Cosmology and Gravitation Title: Non-Gaussianity from non-linear effects in CMB Key Words: CMB, Non-Gaussianity, Cosmological perturbations Abstract: Non-Gaussian effects in the cosmic microwave background (CMB) can arise either from the primordial phase of the universe or from the subsequent non-linear evolution. I will present the different physical effects at play around the last-scattering surface of CMB. I will then discuss the implications for the detection of non-Gaussianity by Planck, presenting both analytical and numerical results.
