Abstract

In this paper, we discuss the potential importance of measuring the CMB anistropy 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. While this effect is undetectable, we show in a companion paper that the combination of lensing and the Sunyaev-Zel'dovich effect produces a detectable signal.
