Scientific paper

We propose a new interpretation for the CO emitting region of the Cloverleaf (H1413+1143), a gravitationally lensed QSO. We proceed by fitting a two-galaxy lensing model directly to the IRAM CO(7-6) data rather than to the optical HST image. From the fit we infer that the CO source might be a disk-like structure with a characteristic radius R >= 790;pc (in the currently widely accepted cosmology: cosmological constant Ω Λ =0.7, matter content Ω m=0.3, and Hubble constant H0=65;km;s-1;mpc}{-1), a value similar to that of the CO emitting regions present in nearby starburst ultraluminous infrared galaxies.
