PAMELA data and leptonically decaying dark matter
Peng-fei Yin, Qiang Yuan, Jia Liu +4
Recently PAMELA released their first results on the positron and antiproton ratios. Stimulated by the new data, we studied the cosmic ray propagation models and calculated the seco…
Determining Cosmological Parameters with Latest Observational Data
Jun-Qing Xia, Hong Li, Gong-Bo Zhao +1
In this paper, we combine the latest observational data, including the WMAP five-year data (WMAP5), BOOMERanG, CBI, VSA, ACBAR, as well as the Baryon Acoustic Oscillations (BAO) an…
Evolution of Metric Perturbations in Quintom Bounce model
Yi-Fu Cai, Xinmin Zhang
We in the paper study the metric perturbations generated in a bouncing universe driven by the Quintom matter. Firstly, we review the background evolution of Quintom Bounce and the…
A Model Of Inflationary Cosmology Without Singularity
Yi-Fu Cai, Tao-tao Qiu, Jun-Qing Xia +1
In this letter, we propose a model of inflationary cosmology with a bounce preceded and study its primordial curvature perturbations. Our model gives rise to a primordial power spe…
Oscillating universe with quintom matter
Hua-Hui Xiong, Yi-Fu Cai, Taotao Qiu +2
In this paper, we study the possibility of building a model of the oscillating universe with quintom matter in the framework of 4-dimensional Friedmann-Robertson-Walker background.…
Constraining Slow-Roll Inflation in the Presence of Dynamical Dark Energy
Jun-Qing Xia, Xinmin Zhang
In this paper we perform a global analysis of the constraints on the inflationary parameters in the presence of dynamical dark energy models from the current observations, includin…
