Description
In this talk, we will give an update about this Cosmology WG project. This project aims to implement a methodology to test theoretical models of the cosmological contributions to the SGWB against residuals potentially found by a Global Fit run. It assumes the release of the posterior for the parameters of a free-form SGWB contribution in the shape of splines (or other interpolation schemes such as GP's). Utilising that output as a posterior predictive, we explore the possibility of inferring constraints for theoretical models of the SGWB. We will probe the limitation of this approach close to the low-signal regime, and try to derive recommendations for optimal free form reconstructions.
