Cosmological simulations of merging galaxies have demonstrated that mergers lead to triggering AGN (active galactic nuclei) and enhanced star-formation. One of the expected outputs of galaxy mergers is pairs of AGN know as dual AGN (DAGN). These systems are important to understand the evolution of galaxy mergers, AGN feedback etc. High-resolution radio or X-ray observations are best ways to confirm the present of DAGN. We have compiled a sample of DAGN candidates from the literature and observed them at multiple frequencies with VLA, UVIT, and GMRT to confirm the nature of the nuclei and their effect on the host galaxies. In this presentation, I will show the results from our multi-wavelength study of dual AGN candidates in detail.
