Abstract

Aims. Ly alpha emitters (LAEs) can be detected out to very high redshifts during the epoch of reionization. The evolution of the LAE luminosity function with redshift is a direct probe of the Ly alpha transmission of the intergalactic medium (IGM), and therefore of the IGM neutral-hydrogen fraction. Measuring the Ly alpha luminosity function (LF) of Lya emitters at redshift z = 7.7 therefore allows us to constrain the ionizing state of the Universe at this redshift.
