Testing the concordance model with large-scale structures
Abstract
With the advancement of data quality and escalating tensions, the cosmological model faces mounting challenges. If these tensions persist and are not attributed to observational systematics, they could precipitate a paradigm shift. In this light, it is important to scrutinize all the hypotheses underlying the model in order to falsify it. In this talk, I will review some of these tests, and focus on joint constraints combining several cosmological probes such as type Ia supernovae, baryon acoustic oscillations, and redshift-space distortion.
