Stacked cutouts and SFR surface density profiles. Top: median stacked cutouts at the position of the QGs in the three redshift bins, at 24 μm (Spitzer/MIPS), 100 and160 μm (Herschel/PACS), 250, 350 and 500 μm Herschel/SPIRE, 850 μm (JCMT/SCUBA-2) and 1.1 mm (ASTE/AzTEC). The white line in each panel has a length of 15”, while the green circles show the beam FWHM in each band. Bottom: Normalised, average SFR surface density (Σ_SFR) profile of the satellites of QGs (circles) in various redshift bins. The error bars correspond to the standard deviation of the surface density in each bin. The pink lines and the shaded regions show the best-fit ‘quenched’ β-models to Σ_SFR and their uncertainties. The vertical grey lines denote the half-width at half-maximum of the MIPS and SPIRE beams.
