Notes. (1) Galaxy name; (2) spectroscopic redshift as in Table 1; (3–4) CO(J → J − 1) transition and observer frame frequency; (5) CO(J → J − 1) velocity integrated flux; (6) molecular gas mass obtained with αCO = 4.36 M⊙ (K km s−1 pc2)−1; (7) depletion timescale τdep = MH2/SFR; (8) molecular gas-to-stellar mass ratio; (9–10) depletion timescale and molecular gas-to-stellar mass ratio predicted for MS field galaxies with redshift and stellar mass of our targets, following Tacconi et al. (2018). Upper limits are at 3σ. We refer to the text for further details.
( † )The reported MH2 of M2129 is estimated from the CO(2→1) flux and has been increased by a factor of two to take into account the possibility that the fit misses a substantial part of the CO(2→1) emission.
