Description

We describe the CO Luminosity Density at High-z (COLDz) survey, the first spectral line deep field targeting CO(1-0) emission from galaxies at z = 1.95-2.85 and CO(2-1) at z = 4.91-6.70. The main goal of COLDz is to constrain the cosmic density of molecular gas at the peak epoch of cosmic star formation. By targeting both a wide (similar to 51 arcmin(2)) and a deep (similar to 9 arcmin(2)) area, the survey is designed to robustly constrain the bright end and the characteristic luminosity of the...[Show more]
