Compilation of observed outflow velocities and radial distances. The symbol indicates the detected gas phase, symbol size – mass outflow rate (Ṁ). The colour indicates the AGN luminosity. The oblique continuous line shows the average Ṁ-weighted velocity of molecular outflows shifted by ∆υ_out = 400 km s⁻¹. The horizontal dashed line shows the upper velocity limit for outflows simulated in this work. Data aggregated from compilations in Fiore et al. (2017); Fluetsch et al. (2019); Lutz et al. (2020); Zubovas et al. (2022).
