Constraints on the extensions to the base CDM model from BICEP2, Planck and WMAP
Cheng Cheng, Qing-Guo Huang, Wen Zhao
Recently Background Imaging of Cosmic Extragalactic Polarization (B2) discovered the relic gravitational waves at confidence level. However, the other cosmic microwave backg…
Constraint on inflation model from BICEP2 and WMAP 9-year data
Cheng Cheng, Qing-Guo Huang
Even though Planck data released in 2013 (P13) is not compatible with Background Imaging of Cosmic Extragalactic Polarization (B2) and some local cosmological observations, includi…
The Tilt of Primordial Gravitational Waves Spectra from BICEP2
Cheng Cheng, Qing-Guo Huang
In this paper we constrain the tilt of the spectra of primordial gravitational waves from Background Imaging of Cosmic Extragalactic Polarization (BICEP2) data only. We find $r=0.2…
Hint of relic gravitational waves in the Planck and WMAP data
Wen Zhao, Cheng Cheng, Qing-Guo Huang
Relic gravitational waves (RGWs) leave well-understood imprints on the anisotropies in the temperature and polarization of cosmic microwave background (CMB) radiation. In the TT an…
Constraints on the cosmological parameters from BICEP2, Planck and WMAP
Cheng Cheng, Qing-Guo Huang
In this paper we constrain the cosmological parameters, in particular the tilt of tensor power spectrum, by adopting Background Imaging of Cosmic Extragalactic Polarization (B2), P…
Testing modified gravity models with recent cosmological observations
Wen-Shuai Zhang, Cheng Cheng, Qing-Guo Huang +4
We explore the cosmological implications of five modified gravity (MG) models by using the recent cosmological observational data, including the recently released SNLS3 type Ia sup…
