  Simulations expect an enhanced star-formation and active galactic nuclei
(AGN) activity during galaxy mergers, which can lead to formation of
binary/dual AGN. AGN feedback can enhance or suppress star-formation. We have
carried out a pilot study of a sample of 10 dual nuclei galaxies with
AstroSat's Ultraviolet Imaging Telescope (UVIT). Here, we present the initial
results for two sample galaxies (Mrk 739, ESO 509) and deep multi-wavelength
data of another galaxy (Mrk 212). UVIT observations have revealed signatures of
positive AGN feedback in Mrk 739 and Mrk 212, and negative feedback in ESO 509.
Deeper UVIT observations have recently been approved; these will provide better
constraints on star-formation as well as AGN feedback in these systems.
