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…

Is the cosmic UV background fluctuating at redshift z ~ 6 ?
Jiren Liu, Hongguang Bi, Long-Long Feng +1
We study the Gunn-Peterson effect of the photo-ionized intergalactic medium(IGM) in the redshift range 5< z <6.4 using semi-analytic simulations based on the lognormal model. Assum…
