Number density of luminous non-giant radio galaxies in the Local Universe, as a function of Cosmic Web density. We define these as RGs with 150 MHz radio luminosities l_ν ≥ 10²⁴ W Hz⁻¹, projected proper lengths l_p < l_p, GRG ≔ 0.7 Mpc, and redshifts z < z_max ≔ 0.16. The Cosmic Web densities encompass baryonic and dark matter, are defined on a 2.9 Mpc h⁻¹ scale, and are given relative to the cosmic mean. We used flexible voxel method densities here. We show the posterior mean with a shaded −1 to +1 posterior standard deviation range. We also show five individual realisations (grey).
