Statistical features of 21-cm emission from the epoch between reionization and Gunn-Peterson transparency
Ping He, Jiren Liu, Long-Long Feng +2
We investigate the 21 cm emission from the epoch between reionization z_r and Gunn-Peterson transparency z_{gp}. According to the lognormal model of the thermal history around reio…
The Statistical Discrepancy between the IGM and Dark Matter Fields: One-Point Statistics
Jesús Pando, Long-Long Feng, Li-Zhi Fang
We investigate the relationship between the mass and velocity fields of the intergalactic medium (IGM) and dark matter. Although the evolution of the IGM is dynamically governed by…
Temperature and Entropy Fields of Baryonic Gas in the Universe
Ping He, Long-Long Feng, Li-Zhi Fang
(Abridged)The temperature (T) and entropy (S) fields of baryonic gas/IGM are analyzed using simulation samples by a cosmological hydro/N-body code. We show that in the nonlinear re…
Spatial Locality of Galaxy Correlation Function in Phase Space: Samples from the 2MASS Extended Source Catalog
Yicheng Guo, Yao-Quan Chu, Li-Zhi Fang
We analyze the statistical properties and dynamical implications of galaxy distributions in phase space for samples selected from the 2MASS Extended Source Catalog. The galaxy dist…
Running spectral index and mode-mode correlation of inflationary perturbations from off-equilibrium effects
Da-Shin Lee, Li-Zhi Fang, Wolung Lee +1
We study the off-equilibrium effects of inflaton on the dynamics of primordial perturbations in the O(N) model. A self-consistent off-equilibrium formalism is employed to investiga…
Off-equilibrium dynamics of the primordial perturbations in the inflationary universe: the O(N) model
Wolung Lee, Yeo-Yie Charng, Da-Shin Lee +1
Using the O(N) model as an example, we investigate the self-interaction effects of inflaton on the dynamics of the primordial perturbations. When taking interactions into account,…
