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…
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…
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,…
Intermittent Features of the QSO Ly Transmitted Flux: Results from Hydrodynamic Cosmological Simulations
Long-Long Feng, Jesus Pando, Li-Zhi Fang
It has been recently found that the local fluctuations of the QSO's Ly absorption spectrum transmitted flux show spiky structures. This implies that the mass fields of the inter…
