Abstract:

I will talk about how we can stress-test the current standard cosmological model comparing early- vs late-time Universe results. Then I will describe how we can obtain cosmological information from the late-time Universe, in particular from current and upcoming galaxy survey data. I will focus on a particular combination of large-scale structure and weak gravitational lensing measurements, the so-called 3x2pt analysis, for which I will discuss its current limitations and potential future directions.
