ABSTRACT

Three-point statistics play a key role in the investigation of the properties of the universe. This talk addresses the modelling of three-point correlation functions (3PCF) in Galaxy Clustering analysis, in the context of current and upcoming generations of cosmic surveys such as Euclid, DESI, LSST and the Roman Telescope. Particular attention will be given to second-order modelling within a perturbative expansion framework, bridging the gap with theory developed in Fourier space, thus enabling the use of the 3PCF to extract cosmological information in non-linear regimes and providing a direction for combining the 3PCF and bispectrum to mitigate potential systematics in cosmological data analysis.
