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…
Perturbations of the Quintom Models of Dark Energy and the Effects on Observations
Gong-Bo Zhao, Jun-Qing Xia, Mingzhe Li +2
We study in this paper the perturbations of the quintom dark energy model and the effects of quintom perturbations on the current observations. Quintom describes a scenario of dark…
Oscillating Quintom and the Recurrent Universe
Bo Feng, Mingzhe Li, Yun-Song Piao +1
Current observations seem to mildly favor an evolving dark energy with the equation of state getting across -1. This form of dark energy, dubbed Quintom, is studied phenomenologica…
An inflation model with large variations in spectral index
Bo Feng, Mingzhe Li, Ren-Jie Zhang +1
Recent fits of cosmological parameters by the Wilkinson Microwave Anisotropy Probe (WMAP) measurement favor a primordial scalar spectrum with varying index. This result, if stands,…
