Narrowband Survey of the GOODS Fields: Search for Lyα Emitters at z = 5.7

We present results from optical narrowband (λc = 8150 Å and Δλ = 120 Å) observations of the Great Observatories Origins Deep Survey (GOODS) fields, using Suprime-Cam on the Subaru Telescope. Using these narrowband data, we then perform a survey of Lyα emitters (LAEs) at z ~ 5.7. The LAE survey covers an area of ≈320 arcmin2 and a comoving volume of ≃8.0 × 104 Mpc3. We found a total of 10 (GOODS-N) and 4 (GOODS-S) LAE candidates at z ~ 5.7. We perform a study of the spatial distribution, space density, and star formation properties of the LAEs at z ~ 5.7.
