abstract
Dark energy interacting with dark matter is a promising model to solve the cosmic coincidence problem. We study the signature of such interaction on large scale cosmic microwave background (CMB) temperature anisotropies. Based on the detail analysis in perturbation equations of dark energy and dark matter when they are in interaction, we find that the large scale CMB, especially the late Integrated Sachs Wolfe effect, is a useful tool to measure the coupling between dark sectors. We also discuss the possibility to detect the coupling by cross-correlating CMB maps with tracers of the large scale structure. We finally perform the global fitting to constrain the coupling by using the CMB power spectrum data together with other observational data. We find that in the $1\sigma$ range, the constrained coupling between dark sectors can solve the coincidence problem.

The model-independent degeneracy-breaking point in cosmological models with interacting Dark Energy and Dark Matter
In interacting dark energy models, the interaction term becomes independent of the constant dark energy equation of state at a specific redshift (about z=1.4), giving a point where the interaction can be observed with...

Quantifying the impacts of future gravitational-wave data on constraining interacting dark energy
Adding 1000 simulated Einstein Telescope standard sirens to current CMB, BAO, and supernova data would tighten H0 and matter density constraints by factors of 2 to 3 in four interacting dark energy models, with modest...
