The Reionization History in the Lognormal Model
Ji-Ren Liu, Li-Zhi Fang, Long-Long Feng +1
We study the evolution of baryonic gas before the reionization in the lognormal (LN) model of cosmic clustering. We show that the thermal history of the universe around the reioniz…
Correlated Hybrid Fluctuations from Inflation with Thermal Dissipation
Wolung Lee, Li-Zhi Fang
We investigate the primordial scalar perturbations in the thermal dissipative inflation where the radiation component (thermal bath) persists and the density fluctuations are therm…
Quasi-Local Evolution of the Cosmic Gravitational Clustering in Halo Model
Long-Long Feng, Li-Zhi Fang
We show that the nonlinear evolution of the cosmic gravitational clustering is approximately spatial local in the - (position-scale) phase space if the initial perturbations…
Hydrogen Clouds before Reionization: a Lognormal Model Approach
Hongguang Bi, Li-zhi Fang, Longlong Feng +1
We study the baryonic gas clouds (the IGM) in the universe before the reionization with the lognormal model which is shown to be dynamcially legitimate in describing the fluctuatio…
The Multiphase Intracluster Medium in Galaxy Groups Probed by the Lyman Alpha Forest
Hu Zhan, Li-Zhi Fang, David Burstein
The case is made that the intracluster medium (ICM) in spiral-rich galaxy groups today probably has undergone much slower evolution than that in elliptical-rich groups and clusters…
Power spectrum and intermittency of the transmitted flux of QSOs Ly-alpha absorption spectra
Priya Jamkhedkar, Long-Long Feng, Wei Zheng +3
Using a set of 28 high resolution, high signal to noise ratio (S/N) QSO Ly-alpha absorption spectra, we investigate the non-Gaussian features of the transmitted flux fluctuations,…
