Abstract:
We study zCOSMOS-bright optical spectra for 609 Spitzer MIPS
24um-selected galaxies with S24um>0.30mJy and I<22.5 (AB mag)
over 1.5deg2 of the COSMOS field.
Description:
The zCOSMOS survey (Lilly et al., 2007, Cat. J/ApJS/172/70) is a very
large spectroscopic program being performed with VIMOS on the VLT. We
cross-correlated the SCOSMOS-shallow 24um catalog with the
zCOSMOS-bright parent catalog. The SCOSMOS survey (Sanders et al.,
2007ApJS..172...86S 2007ApJS..172...86S) comprises IRAC 3.6, 4.5, 5.8, and 8.0um and MIPS
24, 70, and 160um observations including the entire 2deg2 of the
COSMOS-ACS field, as part of the Spitzer Cycle 2 and 3 Legacy Programs.
