Profiles of cosmic filaments since z=4.0 in cosmological hydrodynamical simulation
Weishan Zhu, Fupeng Zhang, Long-Long Feng
A large portion of the baryons at low redshifts are still missing from detection. Most of the missing baryons are believed to reside in large scale cosmic filaments. Understanding…
The dispersion measure and scattering of FRBs: Contributions from the intergalactic medium, foreground halos, and hosts
Weishan Zhu, Long-Long Feng
We investigate the dispersion measure(DM) and scattering of FRBs by the intergalactic-medium(IGM), foreground and host halos, using cosmological hydrodynamical simulation. We find…
Turbulence-induced deviation between baryonic field and dark matter field in the spatial distribution of the Universe
Hua-Yu Yang, Ping He, Weishan Zhu +1
The cosmic baryonic fluid at low redshifts is similar to a fully developed turbulence. In this work, we use simulation samples produced by the hybrid cosmological hydrodynamical/N-…
Barred galaxies in the Illustris-1 and TNG100 simulations
Ze-Bang Zhou, Weishan Zhu, Yang Wang +1
We carry out a comparison study on the bar structure in the Illustris-1 and TNG100 simulations. At , 8.9\% of 1232 disc galaxies with stellar mass in Ill…
The temperature of IGM at high redshifts: shock heating and high mach problem
Junyi Jia, Weishan Zhu, Liang Gao +1
The thermal history of cosmic gas in the Dark Ages remains largely unknown. It is important to quantify the impact of relevant physics on the IGM temperature between and $z…
The scattering of FRBs by the intergalactic medium: variations, strength and dependence on dispersion measures
Weishan Zhu, Long-Long Feng, Fupeng Zhang
The scattering of fast radio bursts (FRBs) by the intergalactic medium (IGM) is explored using cosmological hydrodynamical simulations. We confirm that the scattering by the clumpy…
