Median stacked cutouts (3″ × 3″) of LRDs in NIRCam (7; from f090w to f444w), MIRI (8; from f560w to f2550w), and ALMA/B6 (1.1 mm) bands. All NIRCam and MIRI images have the same pixel size (0.06″). Each cutout reports the corresponding PSF’s FWHM (white circle) and the number of stacked sources. To ease visualization, a smoothing with a Gaussian kernel was applied to all MIRI images, with a larger radius for larger FWHM: two pixels for f560w, f770w, and f1000w; three pixels for f1280w and f1500w; four pixels for f1800w and f2100w, and five pixels for f2550w. The stacked ALMA/B6 image was obtained in the uv-plane and imaged at 0.1″/px scale. Except for MIRI/f2550w and ALMA/B6, all other median stacks lead to a S/N > 3 detection.
