Planck satellite analysis has yielded the first quantitative reconstruction of the bispectrum of the Universe in both CMB
temperature and polarisation (or equivalently the three-point correlator). This has led to a number of stringent constraints
on primordial theoretical models and the beginnings of more powerful joint analysis with the power spectrum. The award-winning
Modal numerical methods that have led to some of these advances will be described, along with current and future application
to large-scale structure and huge galaxy surveys.
N.B. Seminar will be in the Grand Auditoire in the Ecole de Physique (entrance on 1'st floor)
