Description

CMB non-Gaussianity can be used to discriminate between models of the early universe. However, the primordial signal will be biased by intrinsic non-linearties. I will compute the CMB 3-p function generated by second-order effects at recombination and discuss their observability and contamination to measurement of primordial signal.
