Abstract: I will present the theoretical framework to understand the non-Gaussianities in the Hubble-Lemaître diagram emerging from relativistic simulations. With these analytic results, I will discuss which kind of non-Gaussianity can be addressed to intrinsic non-linear effects, such as post-Born corrections and higher-order statistic, against spurious effects introduced by the binning in redshift along the data analysis.
