Molecular gas is the key ingredient for star formation. We have recently demonstrated through CO observations that typical, near-IR selected galaxies at z~1.5 host giant reservoir of molecular gas, implying star formation efficiencies similar to those of local spirals, and are enough luminous in CO to be detected with the current instrumentation. I’ll present the results of our ongoing surveys with the PdBI and VLA interferometers, including the observations of a larger sample, the determination of the gas spatial scales, the search for cold and warm gas components. I’ll discuss implications for the nature of star formation in massive high-z galaxies, and for the future surveys with ALMA and EVLA .
