Search for Non-Gaussianities in the WMAP Data with the Scaling Index Method

Figure 1

WMAP 3-year data after application of the transformation into a three-dimensional point distribution. In the first and the third plots, the full set of points is presented, while the second and fourth show an 𝑥, 𝑧-projection of only the points with |𝑦|<0.05. Two different adjustment parameters were used, 𝑎=0.075 (a) and 𝑎=0.225 (b). The black circles represent the scaling ranges 𝑟=0.075 and 𝑟=0.225. Figure taken from [32].
