Properties of the SUPER sample highlighting the three targets of this work. Left: Bolometric luminosity (L_bol) vs. radio power at 1.4 GHz. The color bar shows the q_24obs parameter, where q_24obs = log(S_24 μm/S_r). S_24 μm and S_r are the observed 24 μm and 1.4 GHz flux densities. Middle: q_24obs parameter vs. redshift. The color bar shows the bolometric luminosity. The solid line represents the typical values for a star-forming galaxy (M32; from Bonzini et al. 2013), while the dashed lines indicate the ±2σ dispersion, which marks the locus of star-forming galaxies. Right: FIR luminosities vs. radio power at 1.4 GHz. The solid line is from Magnelli et al. (2015) and the dashed lines represent 2σ relative to the solid line. The color bar shows the bolometric luminosity.
