ΔsSFR, the logarithmic difference between the specific SFR and the specific SFR of objects lying on the MS and at the same redshift, versus stellar mass M_* (see Delvecchio et al. 2017, for details on SFR calculation) shown on the left, and versus redshift z on the right. Symbols: red circles are the multi-component objects classified as AGN at 3 GHz VLA-COSMOS (objects that exhibit jets or lobes), as shown in Table A.1; blue stars are multi-component SFGs (see Sect. 2 for classification); green circles or stars are multi-component objects with uncertain classification (see Sect. 3.1), with circles used for AGN and stars for SFG based on the radio excess flag (see Sect. 3.1); the blue contours represent the single-component SFGs (objects that show no radio excess; Delvecchio et al. 2017) and the red contours are for single-component AGN (radio excess objects). The black solid and dashed lines show the main sequence for star-forming galaxies and its dispersion (Whitaker et al. 2012).
