The radio galaxy RC J0311+0507 was investigated in the “Big Trio” project, which aims to search for distant radio galaxies. Optical spectroscopy performed at the 6-m telescope measured its redshift as 4.514. The source is one of the most luminous objects in the high redshift Universe having L ≈ 3 × 1029W Hz-1 at 500 MHz, that suggests the presence of a super massive black hole with a mass of about 1010 M⊙ inside the parent galaxy. Mechanisms of the formation of galaxies with black holes of such masses in the early stage of the Universe is not yet clear. Based on a collection of deep images taken in 10 optical and infrared bands we started a photometric study of the environment of this radio galaxy to detect possible neighborhood.
