Abstract

Limited by the coarse angular resolutions and/or the poor sensitivities of the previous generation (sub)millimeter telescopes (SMT, CSO, IRAM, SMA, Herschel, Planck), significant efforts and resources have been devoted to improving the constraints on a few "macro phenomenological correlations", such as the star-formation (e.g., Kennicutt-Schmidt law), Larson's laws, etc. While these laws are almost treated as fundamental physics laws, and have been routinely compared with any new observational measurements, the micro physics including how the stellar cluster-formation is related to an interplay between the supersonic gas motions and self-gravitational contractions, remain poorly understood. As an example, the meaning of the term "turbulence" has been rather ambiguous for the community of star-formation. In this talk, I will present our preliminary developments about how images of molecular cloud structures with extremely high spatial and intensity dynamic ranges may enable discriminating a variety of physical conditions, and how such developments can be prosecuted with the facilities of Taiwan and EAO.
