Functional form of the incidence of complex-morphology radio AGN versus λ_Jet

Characterize the functional form of the incidence of complex-morphology radio AGN as a function of specific black hole kinetic power (λ_Jet), determining whether it follows a power law or exhibits a high-power upturn and quantifying any mass dependence, using larger-volume samples of high-power sources.

Background

The paper finds that compact radio AGN incidence follows a near-constant-slope power law versus λ_Jet, whereas including complex morphologies reveals a boosted incidence at high λ_Jet. This suggests potentially different underlying physics or selection effects for complex sources.

Due to limited statistics and volume, the authors state that a larger sample is required to properly determine the functional form of the incidence for complex morphologies and leave this as future work.
