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…
Investigating the Disk-Corona Relation in a Blue AGN Sample
Jie-Ying Liu, B. F. Liu
We compile a blue AGN sample from SDSS and investigate the ratio of hard X-ray to bolometric luminosity in dependence on Eddington ratio and black hole mass. Our sample comprises 2…
Testing Oscillating Primordial Spectrum and Oscillating Dark Energy with Astronomical Observations
Jie Liu, Hong Li, Junqing Xia +1
In this paper we revisit the issue of determining the oscillating primordial scalar power spectrum and oscillating equation of state of dark energy from the astronomical observatio…
