Feynman graph representation of an algorithm based on information field theory to estimate the level of non‐Gaussianity in the Cosmic Microwave Background, which is shown in the background. As described by Enßlin in article number andp.201800127 , each of the diagrams expresses a term that depends on the data in a non‐linear way and has to be evaluated numerically. The terms are combined by addition and division.
