Diagram showing the nuclear hydrogen column densities against the Eddington ratios for the GATOS Seyferts. The hydrogen column densities are from ALMA CO(3−2) based H₂ estimates at the AGN position from GB21. The symbols are color-coded in terms of the intrinsic 2−10 keV luminosities. The different symbols indicate the mid-IR morphologies (see Table 2). Circinus and NGC 1068, which are marked with star symbols, also show polar mid-IR emission but are not included in our sample. The error bars represent typical uncertainties in the observations, namely, 0.3 dex for the Eddington ratios and a 15% uncertainty in the absolute flux calibration of the ALMA data. Below the solid curve from Fabian et al. (2008) is the blowout region where outflows are likely to clear material in the nuclear regions (see also Ricci et al. 2017b). The dashed line from Venanzi et al. (2020) indicates the limit where the AGN radiation acceleration balances gravity and the IR radiation pressure dominates giving rise to polar dusty outflows. Their radiation-dynamical simulations were for a column density range N_H ≃ 10²³ − 10²⁴ cm⁻², which we mark with the thicker dashed line.
