Abstract : Dual Active galactic nuclei (DAGN) or supermassive black hole (SMBH) pairs are expected to form during galaxy mergers and minor accretion events. High-resolution radio or X-ray observations are the best way to confirm their presence. We aim to study DAGN candidates and probe their effects on galaxy evolution. Studying them provides inputs on SMBH growth, AGN jet production as well as AGN feedback on their host galaxies and environments. We have done observations of a merger system which shows two cores (say, source 1 and source 2) in radio, optical, infrared and UV wavebands. The observations are obtained from expanded very large array (EVLA), Ultra-violet imaging telescope (UVIT), Himalayan Chandra Telescope (HCT) and Giant Metrewave Radio Telescope (GMRT). Our results show the signature of AGN in both the nuclei. However, the presence of star-forming nuclei in source 1 can not be ruled out with our present data. We have detected star-forming knots very near to the centre of source 2 which can be induced by ongoing merger or AGN feedback. In this presentation, we will show the results of this multi-wavelength study in detail.
