Following the success of the Plateau de Bure high-z Blue Sequence Survey(PHIBSS), we present the PHIBSS2 legacy program, a survey of the molecular gasproperties of star-forming galaxies on and around the star formation mainsequence (MS) at different redshifts using NOEMA. This survey significantlyextends the existing sample of star-forming galaxies with CO molecular gasmeasurements, probing the peak epoch of star formation (z=1-1.6) as well as itsbuilding-up (z=2-3) and winding-down (z=0.5-0.8) phases. The targets are drawnfrom the GOODS, COSMOS, and AEGIS deep fields and uniformly sample the MS inthe stellar mass (M*) - star formation rate (SFR) plane with log(M*/Msun) =10-11.8. We describe the survey strategy and sample selection before focusingon the results obtained at z=0.5-0.8, where we report 60 CO(2-1) detections outof 61 targets. We determine their molecular gas masses and separately obtaindisc sizes and bulge-to-total (B/T) luminosity ratios from HST I-band images.The median molecular gas-to-stellar mass ratio, gas fraction, and depletiontime as well as their dependence with M* and offset from the MS followpublished scaling relations for a much larger sample of galaxies spanning awider range of redshifts. The galaxy-averaged Kennicutt-Schmidt (KS) relationbetween molecular gas and SFR surface densities is strikingly linear, pointingtowards similar star formation timescales within galaxies at any given epoch.In terms of morphology, the molecular gas content, the SFR, the disc stellarmass, and the disc molecular gas fraction do not seem to correlate with B/T andthe stellar surface density, which suggests an ongoing supply of freshmolecular gas to compensate for the build-up of the bulge. Our measurements donot yield any significant variation of the depletion time with B/T and hence nostrong evidence for morphological quenching within the scatter of the MS.
