Scaling Relation between Sunyaev-Zel'dovich Effect and X-ray Luminosity and Scale-Free Evolution of Cosmic Baryon Field
Qiang Yuan, Hao-Yi Wan, Tong-Jie Zhang +3
It has been revealed recently that, in the scale free range, i.e. from the scale of the onset of nonlinear evolution to the scale of dissipation, the velocity and mass density fiel…
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…
21 cm Signals from Early Ionizing Sources
Jiren Liu, Jing-Mei Qiu, Long-Long Feng +2
We investigate the 21 cm signals from the UV ionizing sources in the reionization epoch. The formation and evolution of 21 cm emission and absorption regions depend essentially on…
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…
A Unified Fitting of HI and HeII LyαTransmitted Flux of QSO HE2347 with LCDM Hydrodynamic Simulations
Jiren Liu, Priya Jamkhedkar, Wei Zheng +2
Using cosmological hydrodynamic simulations of the LCDM model, we present a comparison between the simulation sample and real data sample of HI and HeII Lyαtransmitted flux in the…
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…
