Receipt: # 407-4 ----- Attempting Submission 5 (Sat Apr 09 00:00:48 GMT 2016) ----- The massive galaxy population at z~2 appears to be quite diverse, ranging from large and clumpy star-forming galaxies to compact quiescent systems. However, the origin of compact quiescent galaxies and their relation to the larger star-forming galaxies are still poorly understood. We have identified a population of dusty, compact star-forming galaxies at z~2 whose structural properties and number densities suggest an evolutionary connection with the first quiescent galaxies. But demonstrating full consistency between progenitor to descendant populations requires verifying that the candidate star-forming progenitors are truly compact in stellar mass and that their SFR is also compact and centrally concentrated (i.e., starburst) rather than distributed in a inside-out growing disk. In the proposed work we will make use of the exquisite image quality and exceptional depth of the CANDELS observations, spanning from the optical-to-NIR, in combination with novel, high-resolution imaging in the far-IR obtained with the submm interferometer ALMA at 870 microns. Together, these datasets will allow the first spatially resolved, self-consistent analysis of the stellar population and dust emission properties of compact SFGs at sub-kpc scales. Moreover, the energy balance between UV and IR luminosities will offer a more direct probe into the effects of dust attenuation, which will allow precise measurements of the physical size and overall distribution of the SFR and stellar mass. Based on those measurements we will constrain the structural evolutionary path of compact SFGs in the mass-size space to confirm if they are indeed direct progenitors of compact quiescent galaxies.
