Probing for dynamics of dark energy and curvature of universe with latest cosmological observations
Gong-Bo Zhao, Jun-Qing Xia, Hong Li +4
We use the newly released 182 Type Ia supernova data combined with the third-year Wilkinson Microwave Anisotropic Probe data (WMAP3) and large scale structure (LSS) information inc…
Probing for variation of neutrino mass with current observations
Gong-Bo Zhao, Jun-Qing Xia, Xinmin Zhang
With the latest astronomical data including Cosmic Microwave Background (WMAP three year, CBI, ACBAR, VSA), Type Ia Supernova ("gold sample"), Galaxy Clustering (SDSS 3-D matter po…
Cosmological neutrino mass limit and the dynamics of dark energy
Jun-Qing Xia, Gong-Bo Zhao, Xinmin Zhang
We investigate the correlation between the neutrino mass limit and dark energy with time evolving equation of state. Parameterizing dark energy as w=w_0+w_1*z/(1+z), we make a glob…
Scale dependence of the primordial spectrum from combining the three-year WMAP, Galaxy Clustering, Supernovae, and Lyman-alpha forests
Bo Feng, Jun-Qing Xia, Jun'ichi Yokoyama
We probe the scale dependence of the primordial spectrum in the light of the three-year WMAP (WMAP3) alone and WMAP3 in combination with the other cosmological observations such as…
Weighing neutrinos in the presence of a running primordial spectral index
Bo Feng, Jun-Qing Xia, Jun'ichi Yokoyama +2
The three-year WMAP(WMAP3), combined with other cosmological observations from galaxy clustering and Type Ia Supernova (SNIa), prefers a non-vanishing running of the primordial spe…
Features in Dark Energy Equation of State and Modulations in the Hubble Diagram
Jun-Qing Xia, Gong-Bo Zhao, Hong Li +2
We probe the time dependence of the dark energy equation of state (EOS) in light of three-year WMAP (WMAP3) and the combination with other tentative cosmological observations from…
Probing Dynamics of Dark Energy with Supernova, Galaxy Clustering and the Three-Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations
Gong-Bo Zhao, Jun-Qing Xia, Bo Feng +1
Using the Markov chain Monte Carlo (MCMC) method we perform a global analysis constraining the dynamics of dark energy in light of the supernova (Riess "Gold" samples), galaxy clus…
Probing Inflation and Dark Energy with Current Cosmological Observations
Jun-Qing Xia, Gong-Bo Zhao, Bo Feng +1
It is commonly believed that our Universe has experienced two different stages of accelerated expansion. The early stage is known as inflation and the current acceleration is drive…
Searching for CPT Violation with Cosmic Microwave Background Data from WMAP and BOOMERANG
Bo Feng, Mingzhe Li, Jun-Qing Xia +2
We search for signatures of Lorentz and violations in the cosmic microwave background (CMB) temperature and polarization anisotropies by using the WMAP and the 2003 flight of…
