RC J1148+0455 identification: gravitational lens or group of galaxies ?
Abstract
The structure of the radio source RC B1146+052 of the ``Cold'' catalogue is investigated by data of the MIT-GB-VLA survey at 4850 MHz. This source belongs to the steep spectrum radio sources subsample of the RC catalogue. Its spectral index is = -1.04. The optical image of this source obtained with 6m telescope is analysed. The radio source center is situated in a group of 8 galaxies of about 24 in the R-filter. The possible explanations of the complex structure of radio components are considered.
