CAMB and bispectrum

Post by Zhou bingchen » February 07 2023

Hello,

I'm trying to calculate the amplitudes given by the primordial bispectrals predicted by different cosmological models,and I want use CAMB to calculate

but,I'm not familiar with this software package,so hope to get your help.

How to use CAMB model to calculate the prediction of CMB bispectrum,or which part of the module tells me that it can calculate the bispectrum.

best,
bingchen

You'd need to run the fortran code. See the sample .ini file for description of some of the input parameters.
