Early dark energy and its interaction with dark matter

Pu, Bo-Yu, Xu, Xiao-Dong, Wang, Bin et al.

Understand

We study a class of early dark energy models which has substantial amount of dark energy in the early epoch of the universe.

  • We examine the impact of the early dark energy fluctuations on the growth of structure and the CMB power spectrum in the linear approximation.
  • Furthermore we investigate the influence of the interaction between the early dark energy and the dark matter and its effect on the structure growth and CMB.
  • We finally constrain the early dark energy model parameters and the coupling between dark sectors by confronting to different observations.
