Dependence of radio detection (Table B.5) on the Sérsic index (n) and stellar mass of the bulge (M_∗,bulge), Table B.2. Filled circles show the galaxies in our sample that are radio detected with e-MERLIN at 1.5 GHz, whereas open circles are for undetected galaxies. Core-Sérsic galaxies are enclosed in blue boxes and 7/20 (35%) of them are undetected with e-MERLIN at 1.5 GHz. For comparison, the radio detection rate with e-MERLIN at 1.5 GHz for the full LeMMINGs sample of 280 galaxies is 44%. Radio-loud galaxies are enclosed in orange diamonds. A representative error bar is shown at the bottom.
