本文讨论了测量CMB各向异性双谱的重要性。我们开发了一个计算的双谱和测量它从微波背景图的形式主义。作为一个例子,我们计算了二阶Rees-Sciama效应产生的双谱,发现这在当前和即将到来的任务中是无法检测到的。
In this paper, we discuss the potential importance of measuring the CMB anisotropy bispectrum. We develop a formalism for computing the bispectrum and for measuring it from microwave background maps. As an example, we compute the bispectrum resulting from the 2nd order Rees-Sciama effect, and find that is undetectable with current and upcoming missions.
