Simultaneous Dependence of Matter Clustering on Scale and Environment
Yun Wang, Ping He
In this work, we propose new statistical tools that are capable of characterizing the simultaneous dependence of dark matter and gas clustering on the scale and the density environ…
The spatial distribution deviation and the power suppression of baryons from dark matter
Hua-Yu Yang, Yun Wang, Ping He +2
The spatial distribution between dark matter and baryonic matter of the Universe is biased or deviates from each other. In this work, by comparing the results derived from Illustri…
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-…
Constraining the optical depth of galaxies and velocity bias with cross-correlation between kinetic Sunyaev-Zeldovich effect and peculiar velocity field
Yin-Zhe Ma, Guo-Dong Gong, Ning Sui +1
We calculate the cross-correlation function between the kinetic Sunyaev-Zeldovich (kSZ) effect and the reconstructed pecu…
Constraining cosmology with pairwise velocity estimator
Yin-Zhe Ma, Min Li, Ping He
In this paper, we develop a full statistical method for the pairwise velocity estimator previously proposed, and apply Cosmicflows-2 catalogue to this method to constrain cosmology…
Fluid-like entropy and equilibrium statistical mechanics of self-gravitating systems
Dong-Biao Kang, Ping He
The statistical mechanics of self-gravitating systems has not been well understood, and still remains an open question so far. In a previous study by Kang & He, we showed that the…
