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…
Cosmological CPT Violation, Baryon/Leptogenesis and CMB Polarization
Mingzhe Li, Jun-Qing Xia, Hong Li +1
In this paper we study the cosmological CPT-violation and its implications in baryo/leptogenesis and CMB polarization. We propose specifically a variant of the models of gravitatio…
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…
