Query: Resolving IRAS 09111-1007 at 350 microns - a different path to ULIRG
  formation?   We have resolved the ultraluminous infrared galaxy (ULIRG), IRAS 09111-1007,
with the new 350 micron-optimised Second Generation Submillimeter High Angular
Resolution Camera (SHARC II) and present the first submillimetre fluxes and
images for the system. IRAS 09111-1007 comprises two interacting luminous
infrared galaxies (LIRGs) with a projected nuclear separation of 39 kpc. The
Western galaxy is roughly four times more luminous in the submillimetre than
its Eastern counterpart. It is an extremely bright LIRG with an AGN. The
classification of the Eastern source is uncertain: it could be a Seyfert 2
galaxy or a LINER. We highlight IRAS 09111-1007 as a system that necessitates
further study: a double AGN ULIRG whose molecular gas content differs from
other widely separated pairs and whose ULIRG phase might not be explained by
current multiple merger and/or final stage ULIRG scenarios.
