Description
Supermassive black hole (SMBH) binaries form due to galaxy mergers. The final coalesce of such SMBH pairs are the sources of gravitational waves. When the SMBHs are accreting, they form pair of AGN which are known as dual or binary AGN. A large sample of AGN pairs at different separations can help us to understand the SMBH growth as well as the evolution of galaxies. However the number of such dual/binary AGN with separation ¡ 10 kpc is still limited. We have searched for such binary/dual AGN in a sample galaxies using multi-band sub-arcsec observations. In this presentation, I will discuss these results in the context of recent advancements (Gaia, Euclid) and highlight the significance of the SKA in this area.
