We report the XMM-Newton discovery of a X-ray bright AGN pair in the interacting galaxy system ESO509-IG066. Both galaxies host an X-ray luminous (LX ~ 1043 erg/s) obscured nucleus with column densities NH ~ 7x1022 and NH ~ 5 x 1021 atoms.cm-2. The optical morphology is only mildly disturbed, suggesting a merging system in the early stage of its evolution. Still, the pair is probably gravitationally bound, and might eventually evolve into a compact, fully gas embedded systems such as NGC6240.Link to publication
