Description
zGAL observed a sample of ~140 bright Herschel-selected sources with NOEMA at 1, 2 and 3 mm, detecting more than 170 individual sources. Each object is detected in at least two emission lines, guaranteeing a 100% redshift success rate. I am going to present the first results of the survey. The spectral energy distributions - finely sampled by NOEMA - are used to derive the dust properties of the sources, namely their dust mass, temperature and emissivity index, as well as to estimate their IR luminosities and SFR. Molecular gas masses are computed from the CO, [CI] and mm continuum tracers. Finally, combining dust and gas results, the sources were positioned in the frame of the Kennicutt-Schmidt and "main sequence" relations, thus drawing some first conclusions about their nature.
