Abstract:
We have carried out a wide-field imaging survey for [OII] 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 6700arcmin2 in the COSMOS field, and a redshift range
between 1.17 and 1.20 (Δz=0.03), corresponding to a survey
volume of 5.56x105Mpc3. We obtain a sample of 3176 [OII] emitting
galaxies with observed emission-line equivalent widths greater than
26Å. Since our survey tends to sample brighter [OII] emitting
galaxies, we also analyze a sample of fainter [OII] emitting galaxies
found in the Subaru Deep Field (SDF). We find an extinction-corrected
[OII] luminosity density of 10Exp(40.35+0.08-0.06)erg/s/Mpc3^,
corresponding to star formation rate density of 0.32+0.06-0.04
M☉/yr/Mpc3 in the COSMOS field at z∼1.2. This is the largest
survey for [OII] emitters beyond z=1 currently available.
Description:
The Cosmic Evolution Survey (COSMOS) is a 2 square degree imaging
survey centered at RA=10:00:28.6, DE=+02:12:21.0 (J2000.0). Our
optical narrow-band imaging observations of the HST COSMOS field have
been made with the Suprime-Cam on the 8.2m Subaru Telescope at Mauna
Kea Observatories.
