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…

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…

Log-Poisson Non-Gaussianity of Ly Transmitted Flux Fluctuations at High Redshift

Yi Lu, Weishan Zhu, Yaoquan Chu +2

We investigate the non-Gaussian features of the IGM at redshift using Ly transmitted flux of quasar absorption spectra and cosmological hydrodynamic simulation of…

Vorticity of IGM Velocity Field on Large Scales

Weishan Zhu, Long-Long Feng, Li-Zhi Fang

We investigate the vorticity of the IGM velocity field on large scales with cosmological hydrodynamic simulation of the concordance model of LCDM. We show that the vorticity field…

Scaling Relation between Sunyaev-Zel'dovich Effect and X-ray Luminosity and Scale-Free Evolution of Cosmic Baryon Field

Qiang Yuan, Hao-Yi Wan, Tong-Jie Zhang +3

It has been revealed recently that, in the scale free range, i.e. from the scale of the onset of nonlinear evolution to the scale of dissipation, the velocity and mass density fiel…
