Turbulence in the Inter-galactic Medium: Solenoidal and Dilatational Motions, and the Impact of Numerical Viscosity
Weishan Zhu, Long-Long Feng, Yinhua Xia +3
We use a suite of cosmological hydrodynamic simulations, run by two fixed grid codes, to investigate the properties of solenoidal and dilatational motions of the intergalactic medi…
Time-Dependent Behavior of Lyman Photon Transfer in High Redshift Optically Thick Medium
Wen Xu, Xiang-Ping Wu, Li-Zhi Fang
With Monte Carlo simulation method, we investigate the time dependent behavior of Ly photon transfer in optically thick medium of the concordance CDM universe. At high redshi…
Effect of Dust on Lyman-alpha Photon Transfer in Optically Thick Halo
Yang Yang, Ishani Roy, Chi-Wang Shu +1
We investigate the effects of dust on Lyα photons emergent from an optically thick medium by solving the integro-differential equation of the radiative transfer of resonant photons…
Intermittence of the Map of Kinetic Sunyaev-Zel'dovich Effect and Turbulence of IGM
Weishan Zhu, Long-Long Feng, Li-Zhi Fang
We investigate the possibility of detecting the turbulent state of the IGM with the kinetic Sunyaev-Zel'dovich (kSZ) effect. Being sensitive to the divergence-free component of the…
Dynamical Effect of the Turbulence of IGM on the Baryon Fraction Distribution
Zhu Weishan, Feng Long-Long, Fang Li-Zhi
We investigate the dynamical effect of the turbulence in baryonic intergalactic medium (IGM) on the baryon fraction distribution. In the fully developed nonlinear regime, the IGM w…
Statistical and dynamical decoupling of the IGM from Dark Matter
Li-Zhi Fang, Weishan Zhu
The mean mass densities of cosmic dark matter is larger than that of baryonic matter by a factor of about 5 in the CDM universe. Therefore, the gravity on large scales should be…
