### Аннотация

To better understand the connection between AGN and their host galaxies, we performed a detailed multi-wavelength analysis of the gravitationally lensed radio-loud AGN MG J0751+2716 at redshift 3.2. This object consists of extended gravitational arcs and two compact components, which are clearly detected in the HST F555W and F814W filters, Keck AO K’-band and EVN observations at 1.65 GHz. By carrying out a pixellated reconstruction of the background source, we spatially locate the stellar population of the AGN host galaxy and the radio core and jets. Our source reconstruction finds that the evolved stellar population is more compact with respect to local early-type galaxies, while the blue component extends several hundreds of parsecs and is off-set from the radio jet.
