We present results from a narrowband optical survey of a contiguous area of 1.95 deg2, covered by the Cosmic Evolution Survey (COSMOS). Both optical narrowband (λc=8150 Å and 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) at z~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 Msolar yr-1 Mpc-3 for LAEs at z~5.7 and compare it with previous measurements.

Abstract
We present results from a narrowband optical survey of a contiguous area of 1.95 deg2, covered by the Cosmic Evolution Survey (COSMOS). Both optical narrowband (λc=8150 Å and 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) at z~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 Msolar yr-1 Mpc-3 for LAEs at z~5.7 and compare it with previous measurements.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
