We derive physical properties of 10 submillimeter galaxies located in the CANDELS coverage of the GOODS-S field .
The galaxies were first identified as submillimeter sources with the LABOCA bolometer and subsequently targeted for 870 \mu m continuum observation with ALMA .
The high angular resolution of the ALMA imaging allows secure counterparts to be identified in the CANDELS multiband dataset .
The CANDELS data provide deep photometric data from UV through near-infrared wavelengths .
Using synthetic spectral energy distributions , we derive photometric redshifts , stellar masses , extinction , ages , and the star formation history .
The redshift range is z = 1.65-4.76 , with two of the galaxies located at z > 4 .
Two SMG counterparts have stellar masses 2-3 orders of magnitude lower than the rest .
The remaining SMG counterparts have stellar masses around 1 \times 10 ^ { 11 } M _ { \odot } .
The stellar population in the SMGs is typically older than the expected duration of the submillimeter phase , suggesting that the star formation history of submillimeter galaxies is more complex than a single burst .
Non-parametric morphology indices suggest that the SMG counterparts are among the most asymmetric systems compared with galaxies of the same stellar mass and redshift .
The HST images shows that 3 of the SMGs are associated with on-going mergers .
The remaining counterparts are isolated .
Estimating the dust and molecular gas mass from the submm fluxes , and comparing with our stellar masses shows that the gas mass fraction of SMGs is \sim 28 % and that the final stellar mass is likely to be \sim ( 1 - 2 ) \times 10 ^ { 11 } M _ { \odot } .
