SDSSJ110546.07+145202.4 is the first known long-duration radio changing-look NLS1 galaxy whose outburst is explained by an accretion-rate change that triggered a powerful radio jet.
J1105+1452 transitioned to a megahertz peaked-spectrum source with a new compact jet of radius ~0.68 pc, apparent velocity ~0.64c, and Doppler factor ~12, while X-ray emission stayed disk-corona dominated.
Galaxies hosting co-spatial radio sources show roughly twice the Compton-y signal at fixed stellar mass compared to those without, persisting to halo scales, with two competing explanations: higher halo mass or AGN thermal energy injection.
VLBA multi-frequency imaging reveals a relativistic, well-collimated jet of ~745 pc in a z=3.4 super-Eddington radio-loud quasar, distinct from low-redshift analogues.
Low-luminosity FRII radio galaxies show higher core prevalence, comparable hotspots, and ~32% restarting/remnant behavior compared to bright FRIIs, revealing a highly diverse population where FRII dynamics occur at low powers.
FR0 radio galaxies are abundant compact sources whose small sizes challenge standard evolutionary models, and SKA observations are expected to clarify their jet physics and demographics.
