The CMB bispectrum from recombination

Download to your calendar using vCal

If you have a question about this talk, please contact Camille Bonvin .

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.
