Dark-ages reionization and galaxy formation simulation -- XXI. Constraining the evolution of the ionizing escape fraction
Simon J. Mutch, Bradley Greig, Yuxiang Qin +2

The Prevalence of Galaxy Overdensities Around UV-Luminous Lyman Emitters in the Epoch of Reionization
E. Leonova, P. A. Oesch, Y. Qin +19
Before the end of the epoch of reionization, the Hydrogen in the Universe was predominantly neutral. This leads to a strong attenuation of Ly lines of galaxies in th…
