We present high-resolution 345-GHz interferometric observations of two extremely luminous (L_ir >~ 10¹³ L_solar), submillimetre-selected galaxies (SMGs) in the Cosmic Evolution Survey (COSMOS) field with the Submillimeter Array (SMA). Both targets were previously detected as unresolved point sources by the SMA
