CMB two- and three-point correlation functions from Alfvén waves
arXiv:1010.4543
Abstract
We study the cosmic microwave background (CMB) temperature fluctuations non-gaussianity due to the vector mode perturbations (Alfvén waves) supported by a stochastic cosmological magnetic field. We present detailed derivations of the statistical properties, two and three point correlation functions of the vorticity perturbations and corresponding CMB temperature fluctuations.
