Power Spectrum and Intermittency of Ly Transmitted Flux of QSO He2347-4342
Priya Jamkhedkar, Long-Long Feng, Wei Zheng +1
We have studied the power spectrum and the intermittent behavior of the fluctuations in the transmitted flux of HE2347-4342 absorption in order to investigate if there…
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…
