Coupled dark energy with perturbed Hubble expansion rate
Weiqiang Yang, Lixin Xu
The coupling between dark sectors provides a possible approach to mitigate the coincidence problem of cosmological standard model. In this paper, dark energy is treated as a fluid…
Reconciling the Tension Between Planck and BICEP2 Through Early Dark Energy
Lixin Xu, Baorong Chang, Weiqiang Yang
We show the possibility that the observational results of the primordial gravitational waves from Planck and BICEP2 for the tensor-to-scalar ratio can be reconciled when an ear…
Testing coupled dark energy with large scale structure observation
Weiqiang Yang, Lixin Xu
The coupling between the dark components provides a new approach to mitigate the coincidence problem of cosmological standard model. In this paper, dark energy is treated as a flui…
Cosmological constraints on interacting dark energy with redshift-space distortion after Planck data
Weiqiang Yang, Lixin Xu
The interacting dark energy model could propose a effective way to avoid the coincidence problem. In this paper, dark energy is taken as a fluid with a constant equation of state p…
