cosmic neutrino background

can you estimate the amplitude of anisotropies in the cosmic neutrino background given the amplitude of CMB anisotropies?

1 comment:

  1. perturbations don't grow in amplitude during radiation domination, so one can expect (ist that really true) the anisotropies in the CNB to be of the same order as those in the CMB, i.e. of order $10^{-5}$.
