A Distance-Deviation Consistency and Model-Independent Method to Test the Cosmic Distance-Duality Relation
C. C. Zhou, J. Hu, M. C. LI +2
A distance-deviation consistency and model-independent method to test the cosmic distance duality relation (CDDR) is provided. The method is worth attention on two aspects: firstly…
Viscous Generalized Chaplygin Gas as a Unified Dark Fluid: Including Perturbation of Bulk Viscosity
Wei Li, Lixin Xu
In this paper, we continue our previous work of studying viscous generalized Chaplygin gas (VGCG) as a unified dark fluid but including the bulk viscosity perturbation. By using th…
Post- constraints on interacting vacuum energy
Yuting Wang, David Wands, Gong-Bo Zhao +1
We present improved constraints on an interacting vacuum model using updated astronomical observations including the first data release from Planck. We consider a model with one di…
Cosmological constraints on a decomposed Chaplygin gas
Yuting Wang, David Wands, Lixin Xu +2
Any unified dark matter cosmology can be decomposed into dark matter interacting with vacuum energy, without introducing any additional degrees of freedom. We present observational…
Modified Chaplygin Gas as a Unified Dark Matter and Dark Energy Model and Cosmic Constraints
Lixin Xu, Yuting Wang, Hyerim Noh
A modified Chaplygin gas model (MCG), , as a unified dark matter model and dark energy model is constrained by using c…
Inhomogeneous vacuum energy
David Wands, Josue De-Santiago, Yuting Wang
Vacuum energy remains the simplest model of dark energy which could drive the accelerated expansion of the Universe without necessarily introducing any new degrees of freedom. Inho…
