We present Atacama Large Millimeter/submillimeter Array (ALMA) CO(J = 2 − 1) observations of two main-sequence star-forming galaxies at z ∼ 1.47 taken from the High-Z Emission Line Survey (HiZELS). These two systems have been previously reported to be molecular gas rich fH2 ≡ MH2 /(MH2 + M⋆) ∼ 0.8. We carried out a follow-up study to resolve, at ∼kpc-scales, the CO emission. These new observations are combined with our earlier ALMA observations (sensitive to diffuse CO emission) and compared…
