We report the detection of CO(2-1) emission from the z=1.2 ultraluminousinfrared galaxy (ULIRG) GOODS J123634.53+621241.3 (also known as thesub-millimeter galaxy GN26). These observations represent the first discoveryof high-redshift CO emission using the new Combined Array for Research inMillimeter-Wave Astronomy (CARMA). Of all high-redshift (z>1) galaxies withinthe GOODS-North field, this source has the largest far-infrared (FIR) fluxobserved in the Spitzer 70um and 160um bands. The CO redshift confirms theoptical identification of the source, and the bright CO(2-1) line suggests thepresence of a large molecular gas reservoir of about 7x10^10 M(sun). Theinfrared-to-CO luminosity ratio of L(IR)/L'(CO) = 80+/-30 L(sun) (K Km/spc^2)^-1 is slightly smaller than the average ratio found in local ULIRGs andhigh-redshift sub-millimeter galaxies. The short star-formation time scale ofabout 70 Myr is consistent with a starburst associated with the merger eventand is much shorter than the time scales for spiral galaxies and estimates madefor high-redshift galaxies selected on the basis of their B-z and z-K colors.
