Low-Redshift Cosmic Baryon Fluid on Large Scales and She-Leveque Universal Scaling
Ping He, Jiren Liu, Long-Long Feng +2
We investigate the statistical properties of cosmic baryon fluid in the nonlinear regime, which is crucial for understanding the large-scale structure formation of the universe. Wi…
X-ray Emission of Baryonic Gas in the Universe: Luminosity-Temperature Relationship and Soft-Band Background
Tong-Jie Zhang, Jiren Liu, Long-long Feng +2
We study the X-ray emission of baryon fluid in the universe using the WIGEON cosmological hydrodynamic simulations. It has been revealed that cosmic baryon fluid in the nonlinear r…
A Parameter-free Statistical Measurement of Halos with Power Spectra
Ping He, Long-Long Feng, Li-Zhi Fang
We show that, in the halo model of large-scale structure formation, the difference between the Fourier and the DWT (discrete wavelet transform) power spectra provides a statistical…
The velocity field of baryonic gas in the universe
Bryan Kim, Ping He, Jesús Pando +2
The dynamic evolution of the baryonic intergalactic medium (IGM) caused by the underlying dark matter gravity is governed by the Navier-Stokes equations in which many cooling and h…
Distributions of the Baryon Fraction on Large Scales in the Universe
Ping He, Long-Long Feng, Li-Zhi Fang
(Abridged) The nonlinear evolution of a system consisting of baryons and dark matter is generally characterized by strong shocks and discontinuities. The baryons slow down signific…
Statistical features of 21-cm emission from the epoch between reionization and Gunn-Peterson transparency
Ping He, Jiren Liu, Long-Long Feng +2
We investigate the 21 cm emission from the epoch between reionization z_r and Gunn-Peterson transparency z_{gp}. According to the lognormal model of the thermal history around reio…
