摘要

We present the SILVERRUSH program strategy and clustering properties investigated with similar to 2000 Ly alpha emitters (LAEs) at z = 5.7 and 6.6 found in the early data of the Hyper Suprime-Cam (HSC) Subaru Strategic Program survey exploiting the carefully designed narrow-band filters. We derive angular correlation functions with the unprecedentedly large samples of LAEs at z = 6-7 over the large total area of 14-21 deg(2) corresponding to 0.3-0.5 comoving Gpc(2). We obtain the average large-scale bias values of b(avg) = 4.1 +/- 0.2 (4.5 +/- 0.6) at z = 5.7 (z = 6.6) for greater than or similar to L* LAEs, indicating a weak evolution of LAE clustering from z = 5.7 to 6.6. We compare the LAE clustering results with two independent theoretical models that suggest an increase of an LAE clustering signal by the patchy ionized bubbles at the epoch of reionization (EoR), and estimate the neutral hydrogen fraction to be x(HI) = 0.15-(+0.15)(0.15) at z = 6.6. Based on the halo occupation distributionmodels, we find that the greater than or similar to L* LAEs are hosted by dark-matter halos with an average mass of log( M-h/M-circle dot ) = 11.1(-0.4)(+0.2) (10.8(-0.5)(+0.3)) at z = 5.7 (6.6) with a Ly alpha duty cycle of 1% or less, where the results of z = 6.6 LAEs may be slightly biased, due to the increase of the clustering signal at the EoR. Our clustering analysis reveals the low-mass nature of greater than or similar to L* LAEs at z = 6-7, and that these LAEs probably evolve into massive super-L* galaxies in the present-day universe.
