Abstract: Using the Very Large Array1 we have made the first detection of the CO J = 1 − 0 line in the sub-millimetre galaxy and extremely red object HR10 at z = 1:44. We find that ∼ 6 × 1010 MSolar of molecular gas is associated with this object, enough to fuel the inferred star-formation rate (∼ 900 MSolar yr−1) over a period of ∼ 107yr. There is tentative evidence that the gas is distributed over tens of kpc, which if confirmed by high-resolution imaging would imply that HR10 is a massive galaxy-sized starburst and not simply a high redshift analogue of a typical Ultra Luminous Infrared Galaxy (ULIRG).
