N2 - We investigate the properties of a sample of 35 galaxies, detected with the Atacama Large Millimeter/Submillimeter Array (ALMA) at 1.1 mm in the GOODS-ALMA field (area of 69 arcmin(2), resolution = 0.60 '', rms similar or equal to 0.18 mJy beam(-1)). Using the ultraviolet-to-radio deep multiwavelength coverage of the GOODS-South field, we fit the spectral energy distributions of these galaxies to derive their key physical properties. The galaxies detected by ALMA are among the most massive at z = 2-4 (M-star,M- med = 8.5 x 10(10)M(circle dot)) and they are either starburst or located in the upper part of the galaxy star-forming main sequence.
