Global fitting analysis on cosmological models after BICEP2
Hong Li, Jun-Qing Xia, Xinmin Zhang
Recently, BICEP2 collaboration has released their results on the measurements of the CMB polarizations. In the framework of the CDM with a power law form of the scalar primordia…
Testing CPT Symmetry with Current and Future CMB Measurements
Si-Yu Li, Jun-Qing Xia, Mingzhe Li +2
In this paper we use the current and future cosmic microwave background (CMB) experiments to test the Charge-Parity-Time Reversal (CPT) symmetry. We consider a CPT-violating intera…
Constraints on Dark Energy from New Observations including Pan-STARRS
Wei Zheng, Si-Yu Li, Hong Li +3
In this paper, we set the new limits on the equation of state parameter (EoS) of dark energy with the observations of cosmic microwave background radiation (CMB) from Planck satell…
Pre-inflationary genesis with CMB B-mode polarization
Zhi-Guo Liu, Hong Li, Yun-Song Piao
Recent B-mode polarization observation seems to imply the tensor tilt at large angular scale, if the primordial signal is dominated. We show that for a primordial un…
Constraints on Cosmological Models from Hubble Parameters Measurements
Wei Zheng, Hong Li, Jun-Qing Xia +3
In this paper, we study the cosmological constraints from the measurements of Hubble parameters--- data. Here, we consider two kinds of data: the direct probe fr…
Evidence for bouncing evolution before inflation after BICEP2
Jun-Qing Xia, Yi-Fu Cai, Hong Li +1
The BICEP2 collaboration reports a detection of primordial cosmic microwave background (CMB) B-mode with a tensor-scalar ratio (68% C.L.). However, this re…
