Abstract

We have carried out a wide-field imaging survey for [O II] λ3727 emitting galaxies at z ≈ 1.2 in the HST COSMOS 2 square degree field using the Suprime-Cam on the Subaru Telescope. The survey covers a sky area of 6700 arcmin 2 in the COSMOS field, and a redshift range between 1.17 and 1.20 (Δz = 0.03), corresponding to a survey volume of 5.56 × 105 Mpc3. We obtain a sample of 3176 [O II] emitting galaxies with observed emission-line equivalent widths greater than 26 Å. Since our survey tends to sample brighter [O II] emitting galaxies, we also analyze a sample of fainter [O II] emitting galaxies found in the Subaru Deep Field (SDF).
