The 1.4 GHz luminosity vs. the SFR of the radio-detected sources in our sample. The red line is the expected radio emission from star formation (Equation (3) in Davies et al. 2017). One index offset from the expectation is plotted as red dashed lines. We have highlighted the radio-loud AGNs with blue squares and other AGNs (Seyferts or broad Hα objects) with green triangles. The gray dotted line represents the radio luminosity beyond which can be considered the undisputed jet origin (Kellermann et al. 2016).
