Inertial effects in covariant gravity impact dark energy dynamics

Parameters related to the affine connection affect the equation of state

Analysis favors zero inertial effect in a flat universe

A closed universe is favored in both LambdaCDM and covariant models

LambdaCDM is more favored than covariant models in non-flat universes

Cosmological constraints on inertial effects in covariant gravity

This paper investigates how inertial effects in covariant gravity models affect cosmological dynamics. The authors find that parameters related to the affine connection can significantly impact the effective dark energy equation of state and drive it to cross the phantom divide line. Their analysis using supernova, cosmic chronometer, BAO and quasar data favors zero inertial effect in a flat universe, and a closed universe in both LambdaCDM and the covariant models. Overall, LambdaCDM is more favored than the covariant models in non-flat universes.
