Abstract

Coupled cosmologies, in order to satisfy CMB constraints, predict values for the cosmological parameters today which may differ substantially from the parameters values within non-interacting cosmologies. In order to fit high-precision CMB data available today, coupled cosmologies can hide their effects at very low redshifts. Therefore, low redshift probes are highly complementary and thus powerful to constrain interacting dark sector models. In this talk we focus on near-universe, low-redshift constraints in a variety of coupled dark matter-dark energy models. We find that current data constrain the dimensionless coupling to be |ξ| < 0.2. We also explore the forecasts for future low redshift probes.
