Abstract

We have detected the CO(2-1) transition from the submillimetre galaxy (SMG) LESSJ033229.4-275619 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 ~=160kms-1) of the CO(2-1) line emission to constrain the gas and dynamical mass of Mgas ~= 1.6 × 1010Msolar and Mdyn(
