Figure 12. FIR excess (Δ logLFIR) vs. radio excess (Δ logL1.4 GHz) for different types of NVSS–SDSS–IRAS galaxies (labeled in each panel) within a redshift range of 0.04–0.3. The FIR and radio excess has been defined as the difference in logarithm of the observed emission and that expected from their SFR, as given by the SED modeling (see Equation (5) and Figure 11 for details). Histograms on the axes show the distributions of the intrinsic Δ logL values. A Gaussian fit to the distribution of star-forming galaxies is also shown in each panel (solid line). In each panel, filled dots represent the galaxies, and the gray scale shows the distribution of star-forming galaxies to guide the eye. Lines of constant q are also shown.
