The Strömgren sphere, the environment and the reionization in the local universe of the highest redshift QSOs
Qingjuan Yu, Youjun Lu
In this paper we investigate the environment and reionization process around the highest redshift QSOs having Gunn-Peterson troughs (z>6.1). Starting with the cosmic density pertur…

The apparent shape of the "Strömgren sphere'' around the highest-redshift QSOs with Gunn-Peterson troughs
Qingjuan Yu
Although the highest redshift QSOs (z>6.1) are embedded in a significantly neutral background universe (mass-averaged neutral hydrogen fraction >1%) as suggested by the Gunn-Peters…
