We present the results of CO(1-0) emission mapping with the IRAM interferometer, at \sim 1 arcsec, resolution, of the z=0.223 ultra-luminous starburst IRAS 11582+3020. This galaxy was selected from an IRAM-30m survey of 30 galaxies at moderate redshift (z \sim 0.2-0.6) to explore galaxy evolution and in particular the star formation efficiency, in the redshift range filling the gap between local and very high-z objects. The CO emission is kinematically resolved, and about 50% of the total emission found in the 27 arcsec (97 kpc) single dish beam is not recovered by the interferometer. This indicates that some extended emission may be present on large scales (typically 7-15 arcsec). The FIR-to-CO luminosity ratio follows the trend between local and high-z ultra-luminous starbursts.< Leer menos
