Stacked cutouts of our sample at 0.8 < z < 1.2, as a function of M_⋆ (left to right, expressed in log M_⊙). Only individual undetected sources (S/N < 3) are stacked. Top, middle and bottom rows: VLA 3 GHz, VLA 1.4 GHz and MIGHTEE 1.3 GHz data, respectively. Each cutout size corresponds to 8 × FWHM of the beam. Below each cutout we report the corresponding S/N of the total stacked flux.
