Abstract (from CDS):

Multi-epoch GHz Very Long Baseline Interferometry (VLBI) data of the radio-loud quasar J1101+7225 were analyzed to estimate the proper motion of extended optically thin jet components. Two components separated from the core could be mapped at 1.66GHz, which is consistent with earlier observations. In one case we found evidence of high apparent superluminal motion (βapp=22.5±4) at large (deprojected) distances to the core (22mas∼4kpc, at z=1.46). Typically in other quasars such high separation velocities are only found much closer to the core component. Furthermore the Doppler factor, the magnetic field strength, and the angular size of the optically thick core were derived using published X-ray data. Analysis of 5GHz VLBI data reveals the existence of further jet components within the central 5mas. Additionally the data published so far on the GHz-spectrum were discussed at all angular resolutions. J1101+7225 turns out to be a standard quasar for studying different aspects of radio jet kinematics out to kpc-scales.
