Recent ALMA study of the lensed SMG SPD.81 has demonstrated the enormous potential of gravitational lensing as a magnifying telescope for studying distant galaxies. Particularly exciting is the prospect of using the magnifying property of lensing to probe star forming activities and gas/dust properties at spatial scales of 100 pc or better (0.01-0.02” resolution without lensing) in these intense starburst systems. Large area surveys using FIR/submm/mm facilities such as Planck, Herschel, and SPT have identified 100’s of candidate lensed SMGs appropriate for such detailed follow-up studies. I will briefly summarize previous works done using SMA in this area of research and the current status on lensed SMG surveys. I will also discuss how the expanded capabilities of wSMA will probe the unexplored parameter space for these extreme starburst systems in the early universe.
