Testing the consistency between cosmological data: the impact of spatial curvature and the dark energy EoS

Understand

The results of joint analyses of available cosmological data have motivated an important debate about a possible detection of a non-zero spatial curvature.

• If confirmed, such a result would imply a change in our present understanding of cosmic evolution with important theoretical and observational consequences.
• In this paper we discuss the legitimacy of carrying out joint analyses with the currently available data sets and explore their implications for a non-flat universe and extensions of the standard cosmological model.
• We use a robust tension estimator to perform a quantitative analysis of the physical consistency between the latest data of Cosmic Microwave Background, type Ia supernovae, Baryonic Acoustic Oscillations and Cosmic Chronometers.
