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…
Observational constraints on a Yang-Mills condensate dark energy model
Z. W. Fu, Y. Zhang, M. L. Tong
Using the recently released Union2 compilation with 557 Type Ia supernovae, the shift parameter of cosmic microwave background given by the WMAP7 observations, and the baryon acous…
Observational constraints on decaying vacuum dark energy model
M. L. Tong, H. Noh
The decaying vacuum model (DV), treating dark energy as a varying vacuum, has been studied well recently. The vacuum energy decays linearly with the Hubble parameter in the late-ti…
Crossing by a single scalar field coupling with matter and the observational constraints
Ming-Lei Tong, Yang Zhang, Zheng-Wen Fu
Motivated by Yang-Mills dark energy model, we propose a new model by introducing a logarithmic correction. we find that this model can avoid the coincidence problem naturally and g…
