Description

In this talk I will present a cosmological analysis of weak lensing data from the Dark Energy Survey using a topological descriptors, persistent homology, within a simulation-based inference framework. This analysis captures cosmological information from the field beyond Gaussian, complementing standard two-point correlation functions.
