« Second-order Boltzmann code and the CMB bispectrum from recombination » |
Zhiqi Huang |
I will introduce CosmoLib2nd, a numerical Boltzmann code at second-order to compute CMB bispectra on the full sky. We compute the cosmic microwave background temperature bispectrum generated by nonlinearities at recombination on all scales. For cosmic-variance limited data to lmax = 2000, its signal-to-noise is S/N=0.47 and will bias a local signal by (fNL)loc~ 0.82. |
