CMB Temperature and Matter Power Spectrum in a Decay Vacuum Dark Energy Model
Lixin Xu, Yuting Wang, Hyerim Noh
In this paper, a decay vacuum model is revisited by detailed analysis of background evolution and perturbation equations. We show the imprints on CMB tempera…

Unified Dark Fluid with Constant Adiabatic Sound Speed and Cosmic Constraints
Lixin Xu, Yuting Wang, Hyerim Noh
As is known above 90% of the energy content in Universe is made of unknown dark component. Usually this dark fluid is separated into two parts: dark matter and dark energy. However…

Probing Ricci dark energy model with perturbations by using WMAP seven-year cosmic microwave background measurements, BAO and Type Ia supernovae
Yuting Wang, Lixin Xu, Yuanxing Gui
In this paper, we investigate the Ricci dark energy model with perturbations through the joint constraints of current cosmological data sets from dynamical and geometrical perspect…
