Radio luminosity as a function of bolometric luminosity for the sources with an IR counterpart and a measured bolometric luminosity (Povich & Whitney 2010; Povich et al. 2016). Triangles represent thermal sources, filled dots depict nonthermal sources, and open circles represent radio sources with an unclassified origin of the radio continuum emission in G14.2. For unclassified radio sources not detected at 3.6 cm we extrapolated the 6 cm flux density to 3.6 cm adopting two values of the spectral index, α = −0.7 and α = +0.5 (see main text). Gray dots show the thermal radio jets compiled by Anglada et al. (2018). The solid black line corresponds to the fit done to all radio jets in Anglada et al. (2018). The red dotted line depicts the radio luminosity at 3.6 cm associated with the Lyman continuum flux of H II regions powered by stars of different luminosities (see Fig. 4 from Sánchez-Monge et al. 2013a). The black dashed line depicts our 5σ sensitivity limit in radio luminosity (~0.02 mJy kpc²).
