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)…
On Dark Energy Isocurvature Perturbation
Jie Liu, Mingzhe Li, Xinmin Zhang
Determining the equation of state of dark energy with astronomical observations is crucially important to understand the nature of dark energy. In performing a likelihood analysis…
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…
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…
