ΣSFR against the ISM pressure set by self-gravity. The PHANGS data correspond to the manually convolved kpc-scale measurements reported by Sun et al. (2020) for 28 nearby galaxies. The ULIRG data correspond to the values measured at ∼350−650 pc scales by Wilson et al. (2019). The DYNAMO data are based on galactic ionized gas velocity dispersion measurements along with spatially unresolved molecular gas observations (Fisher et al. 2019). We also present the ∼kpc-scale values measured for a typical SFG at z ∼ 1.5 (SHiZELS-19; Molina et al. 2019b). The dashed line corresponds to the best fit presented by Fisher et al. (2019) for the DYNAMO and THINGS data, while the solid black line corresponds to the best fit given by Sun et al. (2020) to the PHANGS data. The dot-dashed line corresponds to the parametrization given by Kim et al. (2013) for their set of hydrodynamical simulations. The solid red line represents our best fit. The starburst and ULIRG data are consistent with the trend reported from the nearby galaxies. The z ∼ 1.5 SFG data are in clear offset.
