Violin plots showing the distribution of W₈₀ line widths across all spaxels in the combined sample of radio-quiet quasars observed with JWST/NIRSpec IFU ( G. Cresci et al. 2023; M. A. Marshall et al. 2023; A. Vayner et al. 2024; S. Veilleux et al. 2023, top row). This is compared to the spaxel-level W₈₀ distributions in each of the six HzRGs presented in this work (the second to the seventh row). W₈₀ is a nonparametric measure of the line width and serves as a proxy for the strength of AGN-driven outflows and the degree of kinematic disturbance. The radio-quiet quasars exhibit typical W₈₀ values of ∼600 km s⁻¹, significantly lower than the radio galaxy sample, where median W₈₀ values range from ∼950 to 2100 km s⁻¹, with extended high-velocity tails exceeding 2500 km s⁻¹. This highlights the stronger gas turbulence and outflow activity associated with radio jets.
