Alfvén波的CMB两点和三点关联函数

CMB two- and three-point correlation functions from Alfvén waves

Tina Kahniashvili, George Lavrelashvili

摘要:

研究了由随机宇宙磁场支持的矢量模扰动(阿尔文波)引起的非高斯宇宙微波背景(CMB)温度涨落.详细推导了涡度扰动的统计性质、两点和三点关联函数以及相应的CMB温度涨落。

英文摘要:

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.
