Description
We use the complete, spectroscopic GAMA09 survey to measure the fraction of galaxies hosting radio and X-ray AGN, defined using LOFAR and eROSITA data, as functions of mass-scaled power indicators. We recover the previously found mass-invariant triggering and fueling mechanisms in the incidence of X-ray AGN as a function of λEdd. However, the story is more perplexing in the case of radio AGN, especially when considering different radio morphologies, as their incidence as a function of λJet shows a residual mass and jet power dependence. Interestingly, these effects cannot be explained by more powerful radio AGN residing in more dense environments (or more massive dark matter haloes). We demonstrate that this statistical incidence approach is a powerful way to probe the fundamental accretion physics, in particular the disk-jet connection, in varying accretion modes. Lastly, we compute the average λJet as a function of stellar mass and radio morphology to understand which types of radio AGN exert the most impactful feedback on their host galaxies. This knowledge serves as a useful calibrator for AGN feedback simulations.
