SILVERRUSH. XIII. z=2-7 LAEs from Subaru HSC

We present 20567 Ly{alpha} emitters (LAEs) at z=2.2-7.3 that are photometrically identified by the SILVERRUSH program in a large survey area up to 25deg^2^ with deep images of five broadband filters (grizy) and seven narrowband filters targeting Ly{alpha} lines at z=2.2, 3.3, 4.9, 5.7, 6.6, 7.0, and 7.3 taken by the Hyper Suprime-Cam Subaru Strategic Program and the Cosmic HydrOgen Reionization Unveiled with Subaru survey.

We select secure >5{sigma} sources showing narrowband color excesses via Ly{alpha} break screening, taking into account the spatial inhomogeneity of limiting magnitudes. After removing spurious sources by careful masking and visual inspection of coadded and multiepoch images obtained over the 7yr of the surveys, we construct LAE samples consisting of 6995, 4641, 726, 6124, 2058, 18, and 5 LAEs at z=2.2, 3.3, 4.9, 5.7, 6.6, 7.0, and 7.3, respectively, although the z=7.3 candidates are tentative.
