Abstract

We have detected the CO(2–1) transition from the submillimetre galaxy (SMG) LESS J033229.4−275619 at z= 4.755 using the new Compact Array Broadband Backend system on the Australian Telescope Compact Array. These data have identified a massive gas reservoir available for star formation for the first time in an SMG at z~ 5. We use the luminosity and velocity width (full width at half-maximum, FWHM, of ≃160 km s^(−1)) of the CO(2–1) line emission to constrain the gas and dynamical mass of M_(gas)≃ 1.6 × 10^(10) M_⊙ and Mdyn(<2 kpc) ≃ 5 × 10^(10) (0.25/sin^(2)i) M_⊙, respectively, similar to that observed for SMGs at lower redshifts of z~ 2–4, although we note that our observed CO FWHM is a factor of ~3 narrower than typically seen in SMGs.
