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.
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.
VLBA multi-frequency imaging resolves a collimated jet extending ~745 pc in the z=3.4351 super-Eddington radio-loud quasar ID830, with v ≳ 0.19c and viewing angle ≲ 79° but δ ~ 1.

A VLBA-resolved Jet Associated with Super-Eddington Accretion in a Radio-loud Quasar at $z=3.4$
VLBA multi-frequency imaging resolves a collimated jet extending ~745 pc in the z=3.4351 super-Eddington radio-loud quasar ID830, with v ≳ 0.19c and viewing angle ≲ 79° but δ ~ 1.
