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…
Estimation of the Galaxy Quenching Rate in the Illustris Simulation
Yang Wang, Xuan Liu, Weishan Zhu +2
Quenching is a key topic in exploring the formation and evolution of galaxies. In this work, we study the quenching rate, i.e., the variation in the fraction of quenched galaxies p…
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…
