Cold Dark Matter Isocurvature Perturbations: Cosmological Constraints and Applications

Hong Li, Jie Liu, Jun-Qing Xia +1

In this paper we present the constraints on cold dark matter (CDM) isocurvature contributions to the cosmological perturbations. By employing Markov Chain Monte Carlo method (MCMC)…

Evidences for bouncing evolution before inflation in cosmological surveys

Jie Liu, Yi-Fu Cai, Hong Li

Inflationary cosmology with a preceding nonsingular bounce can lead to changes on the primordial density fluctuations. One significant prediction is that the amplitude of the power…

Dark Energy Perturbations Revisited

Mingzhe Li, Yifu Cai, Hong Li +2

In this paper we study the evolution of cosmological perturbations in the presence of dynamical dark energy, and revisit the issue of dark energy perturbations. For a generally par…

Constraints on Dark Energy Parameters from Correlations of CMB with LSS

Hong Li, Jun-Qing Xia

In this paper, we combine the the latest observational data, including the WMAP five-year data (WMAP5), the baryon acoustic oscillations (BAO) and type Ia supernovae (SN) "union" c…

Entropic cosmology: a unified model of inflation and late-time acceleration

Yi-Fu Cai, Jie Liu, Hong Li

Holography is expected as one of the promising descriptions of quantum general relativity. We present a model for a cosmological system involving two holographic screens and find t…
