“…Models were the interaction reverses sign, IDE are preferred to the concordance model, the Hubble tension is alleviated but the S 8 tension still persists. In [175] the model gives an acceptable value of the Hubble parameter. In [355] Planck 2018 data and local measurements of the Hubble constant indicated the coupling was non-zero at the 3σ C.L.…”

“…IDE models and models with DM or DE self-interaction have also been analyzed [41]. The interaction can be seen as a open thermodynamical system [175]. In [306] the decay rate is constant, similar to radiactive decay.…”

“…By keeping the continuity equation unaltered the background evolution is identical to the concordance model [53,205,223,282,311]. Couplings of DE to baryons [52,330], to radiation [115] and to both DM and ordinary matter [175] have also been considered.…”

The interaction between dark matter and dark energy can be in- corporated into field theory models of dark energy that have proved successful in alleviating the coincidence problem. We review recent advances in this field, including new models and constraints from dif- ferent astronomical data sets. We show that interactions are allowed by observations and can reduce the current tensions among different measurements of cosmological parameters. We extend our discussion to include constraints from non-linear effects and results from cosmo- logical simulations. Finally, we discuss forthcoming multi-messenger data from current and future observational facilities that will help to improve our understanding of the interactions within the dark sector.
