Abstract
We propose a sample of submillimeter galaxies in the GOODS-S field that, through colour selection, are likely to be at high redshift (z>3). We search the AzTEC catalog of sources at 1.1 mm (Scott et al. 2010) and cross-correlate it with the BLAST catalog at 250, 350 and 500μm (Devlin et al. 2009) to select those that, due to their low fluxes (S/N < 3.5σ), have not been included at the BLAST catalogs but of which we do have a signal below the formal limit of detectability (drop-outs).
