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
(
erg s-1) obscured nucleus
with column densities
cm-2 and
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 NGC 6240 ([CITE]).
