The Herschel space mission has generated, for the first time, a rich data set
that allow us to explore the far-IR (FIR) universe at z > 1 on a large scale
that is comparable to those in optical/near-IR. As the mission is now over,
these are the best -- and all -- that we can have before the next generation FIR
facilities arrive. We are undertaking a program to study the extreme,
dust-enshrouded star formation in galaxies at z >1, targeting the
Ultra-Luminous InfraRed Galaxies (ULIRGs) revealed by the Herschel very
wide-field surveys. The most serious challenge is the persisting problem of
poor angular resolution in FIR/sub-mm that the Herschel still suffered. We are
developing a method to extract the major component(s) of Herschel sources using
optical data directly as the position priors, which is appropriate to the
study of ULIRGs. We will construct the largest, well-defined sample of high-z
ULIRG, whose total IR luminosity are directly measured based on multiple FIR
bands, and to enable a slew of follow-up studies. Some preliminary results will
be presented here.
