Presents ultra-low frequency spectral index maps for 22 bright extended radio galaxies showing indices of ~0.5 near cores rising to >1.0 in lobes for FR I sources and 0.5-0.9 in FR II hotspots.
Including radiative losses in analytic models of high-redshift radio galaxies reduces predicted radio and X-ray luminosities compared to models that neglect them.
The paper reviews radio galaxy physics and outlines SKA-enabled studies of jet duty cycles, episodic activity, and dying sources.
