However, UV/optical emission is often affected by dust obscuration, especially at high redshifts where dusty star-forming galaxies (SFGs) dominate the cosmic star formation rate density. To construct a complete picture of the obscured and unobscured star formation and SMBH activity of galaxies over 0.5 < z < 3, we propose to combine archival HST ACS/WFC3 data with deep 10 GHz radio observations obtained with the Karl G. Jansky Very Large Array (VLA) toward the GOODS-N field. The resolution of this new radio map is three times better than that of current deep extragalactic surveys and matches the one of existing HST observations, allowing us to resolve the radio emission of typical SFGs out to z=2 on ~1.7 kpc scales. This HST/VLA data set permits detailed characterization of the rest-frame UV/optical/radio structure of ~300 high-redshift galaxies at a similar resolution, which can be used to derive spatially resolved maps of stellar mass and star formation rate across galactic disks. Using this knowledge, we will investigate (i) the contribution of dust-obscured and unobscured star formation to the stellar mass buildup in high-redshift galaxies, (ii) the UV/optical/radio size evolution of galaxies, and (iii) the mechanisms that trigger and quench star formation across cosmic time.
