Ly Leaks in the Absorption Spectra of High Redshift QSOs
Jiren Liu, Hongguang Bi, Li-Zhi Fang
Spectra of high redshift QSOs show deep Gunn-Peterson absorptions on the blue sides of the \Lya emissions lines. They can be decomposed into components called \Lya leaks, defined t…
Ly Leaks and Reionization
Long-Long Feng, Hong-Guang Bi, Ji-Ren Liu +1
Ly absorption spectra of QSOs at redshifts show complete Gunn-Peterson absorption troughs (dark gaps) separated by tiny leaks. The dark gaps are from the intergalacti…
Non-Gaussianity of the Cosmic Baryon Fluid: Log-Poisson Hierarchy Model
Jiren Liu, Li-Zhi Fang
In the nonlinear regime of cosmic clustering, the mass density field of the cosmic baryon fluid is highly non-Gaussian. It shows different dynamical behavior from collisionless dar…
Estimating Power Spectrum of Sunyaev-Zeldovich Effect from the Cross-Correlation between WMAP and 2MASS
Liang Cao, Jiren Liu, Li-Zhi Fang
We estimate the power spectrum of SZ(Sunyaev-Zel'dovich)-effect-induced temperature fluctuations on sub-degree scales by using the cross correlation between the three-year WMAP map…
