CMB two- and three-point correlation functions from Alfvén waves [PDF]
Tina Kahniashvili, George LavrelashviliWe study the cosmic microwave background (CMB) temperature fluctuations non-gaussianity due to the vector mode perturbations (Alfv\'en 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.View original: http://arxiv.org/abs/1010.4543
