DESCRIPTION:Cosmological probe combination for current and future surveys\n
Different cosmological probes such as the CMB, galaxy clustering and weak lensing carry complementary information and their combination is therefore a powerful way to constrain our cosmological model. Apart from yielding tighter constraints on cosmological parameters, combining different probes also allows for the identification and characterization of systematic uncertainties, which is crucial as we move towards high-precision surveys such as Euclid, LSST and the Simons Observatory.\n
However, cosmological probes have so far mostly been combined at the two-point function level, including mostly large-scale information. In this talk, I will first present a two-point function-based joint analysis of CMB, galaxy clustering and weak lensing, before moving on to talk about our recent work towards including small-scale and non-Gaussian information in joint probe analyses. I will discuss some of the challenges that will need to be overcome and highlight the opportunities offered by these approaches, which will be important for optimally benefitting from the exciting data provided by both ongoing and upcoming surveys.\n
