Abstract

I will describe recent work to quantify the shift in 2 and 3-point correlation functions induced by the relative velocity, present an analytic approach to deriving the matter transfer function showing why the relative velocity has its spatial structure, and conclude with a new 3-point algorithm offering a significant speed advantage over previous works.
