Cluster Lensing Survey in the Millimeter

I will present a 1.3mm continuum survey (IRAM Large Programme) of distant dusty galaxies out to redshift z>5-8. Our strategy is to map out the critical line regions of five galaxy clusters selected for their highly accurate mass models and extensive multi-wavelength dataset (HST, Spitzer IRAC, eMerlin, and Herschel). The 1.3 mm source population at the faintest fluxes (sub-mJy levels) is yet to be discovered, but is expected to dominate the star formation rate density at high redshifts and produce the bulk of the cosmic infrared background (CIB) at this wavelength. Identifying and studying the sub-mJy mm population is one of the core science driver for the future ALMA observatory. However, with the recent development of WIDEX, the Plateau de Bure Interferometer (PdBI) is already able to start investigating the properties of typical star-forming galaxies out to z$\sim$ 8.
