Ratio of density power spectra between hydrodynamic and gravity-only runs for several species. The colours indicate different FLAMINGO models. For comparison, we add the non-radiative run. Left panel: Results at z = 0 for gas (solid lines), dark matter (dashed lines), stars and black holes (dashed double-dotted lines), and total matter (dotted lines). Middle panel: Zoom of the large-scale suppression of four representative FLAMINGO models in the gas (solid lines) and total baryons (dashed-dotted lines) components at z = 0. Right panel: Redshift evolution of the large-scale gas bias, defined as the ratio between gas and gravity-only power spectra at k = 0.01 h/Mpc at each redshift.
