	abstract = {We present multi-band observations of an extremely dusty star-forming lensed galaxy (HERS1) at \$z=2.553\$. High-resolution maps of {\textbackslash}textit\{HST\}/WFC3, SMA, and ALMA show a partial Einstein-ring with a radius of \${\textbackslash}sim\$3\${\textasciicircum}\{{\textbackslash}prime{\textbackslash}prime\}\$. The deeper HST observations also show the presence of a lensing arc feature associated with a second lens source, identified to be at the same redshift as the bright arc based on a detection of the [NII] 205\${\textbackslash}mu\$m emission line with ALMA. A detailed model of the lensing system is constructed using the high-resolution HST/WFC3 image, which allows us to study the source plane properties and connect rest-frame optical emission with properties of the galaxy as seen in sub-millimeter and millimeter wavelengths. Corrected for lensing magnification, the spectral energy distribution fitting results yield an intrinsic star formation rate of about \$1000{\textbackslash}pm260\$ \$\{{\textbackslash}rm M\_\{{\textbackslash}odot\}\}\$yr\${\textasciicircum}\{-1\}\$, a stellar mass \$\{{\textbackslash}rm M\_*\}=4.3{\textasciicircum}\{+2.2\}\_\{-1.0\}{\textbackslash}times10{\textasciicircum}\{11\} \{{\textbackslash}rm M\_\{{\textbackslash}odot\}\}\$, and a dust temperature \$\{{\textbackslash}rm T\}\_\{{\textbackslash}rm d\}=35{\textasciicircum}\{+2\}\_\{-1\}\$ K. The intrinsic CO emission line (\$J\_\{{\textbackslash}rm up\}=3,4,5,6,7,9\$) flux densities and CO spectral line energy distribution are derived based on the velocity-dependent magnification factors. We apply a radiative transfer model using the large velocity gradient method with two excitation components to study the gas properties. The low-excitation component has a gas density \$n\_\{{\textbackslash}rm H\_2\}=10{\textasciicircum}\{3.1{\textbackslash}pm0.6\}\$ cm\${\textasciicircum}\{-3\}\$ and kinetic temperature \$\{{\textbackslash}rm T\}\_\{{\textbackslash}rm k\}=19{\textasciicircum}\{+7\}\_\{-5\}\$ K and a high-excitation component has \$n\_\{{\textbackslash}rm H\_2\}=10{\textasciicircum}\{2.8{\textbackslash}pm0.3\}\$ cm\${\textasciicircum}\{-3\}\$ and \$\{{\textbackslash}rm T\}\_\{{\textbackslash}rm k\}=550{\textasciicircum}\{+260\}\_\{-220\}\$ K. Additionally, HERS1 has a gas fraction of about \$0.4{\textbackslash}pm0.2\$ and is expected to last 250 Myr. These properties offer a detailed view of a typical sub-millimeter galaxy during the peak epoch of star-formation activity.},
