We present recent results from our deep- and wide-field studies of Lyman-α emitters (LAEs) at z=3.1-6.6 in the 1 deg^2 sky of Subaru/XMM Deep Survey (SXDS). The SXDS field has a large contiguous area that provides accurate statistical measurements as well as the panoramic views (˜ 150 × 150 comoving Mpc^2) at high-z.
We find that the ultraviolet (UV) luminosity function of LAEs increases from z=3.1 to 5.7, in contrast to that of dropout galaxies. It indicates the emergence of Lyman-α-emitting population at z˜ 6. The preliminary catalog of our z=6.6 LAEs shows that clustering of LAEs does not significantly change from z=5.7 to 6.6. This clustering evolution places a constraint on the neutral fraction of the intergalactic medium with a theoretical model, which does not prefer the beginning of reionization at z=6-7 but a moderate change of neutral fraction from z≃ 6 to 7.
In the last part of this paper, we introduce on-going high-z galaxy searches using Subaru to study reionization and galaxy formation at z=7-9.
