  "abstract": "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). The galaxy is gravitationally lensed by a massive WISE identified galaxy cluster at $z\\sim1$. The lensed galaxy is spectroscopically confirmed at $z=2.685$ from detection of $\\rm {CO (1 \\rightarrow 0)}$ by GBT and from detection of $\\rm {CO (3 \\rightarrow 2)}$ obtained with CARMA. We use the combined spectroscopic and imaging observations to construct a detailed lens model of the background dusty star-forming galaxy (DSFG) which allows us to study the source plane properties of the target. Multi-band data yields a magnification corrected star formation rate of $1900(\\pm200)\\,M_{\\odot}{\\rm yr^{-1}}$ and stellar mass of $6.8_{-2.7}^{+0.9}\\times10^{11}\\,M_{\\odot}$ consistent with a main sequence of star formation at $z\\sim2.6$. The CO observations yield a molecular gas mass of $8.3(\\pm1.0)\\times10^{10}\\,M_{\\odot}$, 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 DSFG has a very short gas depletion time scale of $\\sim40$ Myr. The high stellar mass and small gas fractions observed indicate that the lensed DSFG 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.",
