Abstract

We present results from a narrowband optical survey of a contiguous area of 1.95 deg ², covered by the Cosmic Evolution Survey (COSMOS). Both optical narrowband (λ _c = 8150 Åand Δλ = 120 Å) and broadband (B, V, g′, r′, i′, and z′) imaging observations were performed with the Subaru prime-focus camera, Suprime-Cam on the Subaru Telescope. We provide the largest contiguous narrowband survey, targeting Lyα emitters (LAEs) atz s ≈ 5.7. We find a total of 119 LAE candidates at z ∼ 5.7. Over the wide-area covered by this survey, we find no strong evidence for large-scale clustering of LAEs. We estimate a star formation rate (SFR) density of ∼7 × 10 ^-4 M _⊙ yr ^-1 Mpc ^-3 for LAEs at z ≈ 5.7 and compare it with previous measurements.
