The advent of the Atacama Large Millimeter/submillimeter Array (ALMA) has enabled us to obtain such maps at sufficiently high spatial resolution to be free from source confusion. We present a new 1.1mm map obtained by ALMA in the SSA22 field. SSA22 contains a remarkable proto-cluster at z=3.09 and is therefore an ideal region to investigate the role of large-scale cosmic web on dust-obscured star formation. The typical 1sigma depth of our map is 73 ","authors_text":"Bunyo Hatsukade, David M.
