The galaxy is gravitationally lensed by a massive WISE-identified galaxy cluster at z ˜ 1. The lensed galaxy is spectroscopically confirmed at z = 2.685 from detection of {CO} (1\to 0) by GBT and from detection of {CO} (3\to 2) obtained with CARMA. We use the combined spectroscopic and imaging observations to construct a detailed model of the background dusty lensed submillimeter galaxy (SMG), which allows us to study the source plane properties of the target. The best-fit lens model provides magnifications of μ star = 2.10 ± 0.11 and μ dust = 2.02 ± 0.06 for the stellar and dust components, respectively. Multiband data yield a magnification-corrected star formation rate of 1900(±200) M ⊙ yr-1 and a stellar mass of {6.8}-2.7+0.9× {10}11 {M}⊙ , consistent with a main sequence of star formation at z ˜ 2.6. The CO observations yield a molecular gas mass of 8.3(±1.0) × 1010 M ⊙, similar to the most massive star-forming galaxies, which together with the high star formation efficiency, are responsible for the intense observed star formation rates. The lensed SMG has a very short gas depletion timescale of ˜40 Myr. The high stellar mass and small gas fractions observed indicate that the lensed SMG likely has already formed most of its stellar mass and could be a progenitor of the most massive elliptical galaxies found in the local universe.

N2 - We present the results of combined deep Keck/NIRC2, HST/WFC3 near-infrared, and Herschel far-infrared observations of an extremely star-forming dusty lensed galaxy identified from the Herschel Astrophysical Terahertz Large Area Survey (H-ATLAS J133542.9+300401).
