Constraints on the generalized Chaplygin gas model including gamma-ray bursts via a Markov Chain Monte Carlo approach
Nan Liang, Lixin Xu, Zong-Hong Zhu
We investigate observational constraints on the generalized Chaplygin gas (GCG) model including the gamma-ray bursts (GRBs) at high redshift obtained directly from the Union2 type…
Cosmography: Supernovae Union2, Baryon Acoustic Oscillation, Observational Hubble Data and Gamma Ray Bursts
Lixin Xu, Yuting Wang
In this paper, a parametrization describing the kinematical state of the universe via cosmographic approach is considered, where the minimum input is the assumption of the cosmolog…
Scattering of scalar perturbations with cosmological constant in low-energy and high-energy regimes
Molin Liu, Benhai Yu, Rumin Wang +1
We study the absorption and scattering of massless scalar waves propagating in spherically symmetric spacetimes with dynamical cosmological constant both in low-energy and high-ene…
Cosmic Constraint to DGP Brane Model: Geometrical and Dynamical Perspectives
Lixin Xu, Yuting Wang
In this paper, the Dvali-Gabadadze-Porrati (DGP) brane model is confronted by current cosmic observational data sets from geometrical and dynamical perspectives. On the geometrical…
Testing the Consistence of Gamma Ray Burst Data-set and Supernovae Union2
Lixin Xu, Yuting Wang
In this paper, we test the consistency of Gamma Ray Bursts (GRBs) Data-set and Supernovae Union2 (SNU2) via the so-called {\it multi-dimensional consistency test} under the assumpt…
Observational Constraints to Ricci Dark Energy Model by Using: SN, BAO, OHD, fgas Data Sets
Lixin Xu, Yuting Wang
In this paper, we perform a global constraint on the Ricci dark energy model with both the flat case and the non-flat case, using the Markov Chain Monte Carlo (MCMC) method and the…
