Multi-wavelength view of the eight high-redshift galaxies of our sample, ordered according to Table 1. From left to right, we present the i- or r-band (HST, VIMOS, and VOICE data), the Spitzer 3.6 μm/VIDEO Ks-band/NICMOS 1.6 μm images, the radio VLA 1.4/3 GHz and the FIR data from ALMA and Herschel, and the red contours correspond to the VLA emission. From top to bottom, the contour levels of the radio image for each source are (7.715 × 10⁻⁶, 2.093 × 10⁻⁵), 2.827 × 10⁻⁵, (−4.710 × 10⁻⁶, 1.058 × 10⁻⁵), 5.640 × 10⁻⁶, (−4.845 × 10⁻⁶, 5.461 × 10⁻⁶), (−5.078 × 10⁻⁶, 1.407 × 10⁻⁵), (−4.633 × 10⁻⁶, 1.124 × 10⁻⁵, 2.712 × 10⁻⁵), and 2.092 × 10⁻⁵ Jy beam⁻¹. Each panel has a size of 7.2 × 7.2 arcsec², except for the Herschel image, which for visualisation purposes has a larger extent. Additionally, the beam size (shaded light grey area) of each instrument and a 2 arcsec scale bar are added in each panel. The ALMA data come from the projects AS2COSMOS and ALESS (Simpson et al. 2020; Hodge et al. 2013).
