Abstract

The radio galaxy RC J0311+0507 was investigated in the “Big Trio” project, which aims tosearch for distant radio galaxies. Optical spectroscopy performed at the 6-m telescopemeasured its redshift as 4.514. The source is one of the most luminous objects in the highredshift Universe having L  ≈  3 × 1029W Hz-1 at 500 MHz, thatsuggests the presence of a super massive black hole with a mass of about1010 M⊙ inside the parent galaxy. Mechanisms ofthe formation of galaxies with black holes of such masses in the early stage of theUniverse is not yet clear. Based on a collection of deep images taken in 10 optical andinfrared bands we started a photometric study of the environment of this radio galaxy todetect possible neighborhood.
