These galaxies are considered to be the progenitors of massive quiescent galaxies at intermediate redshifts ($z\\sim$2) but their stellar structure and buildup is unknown. Here, we present the first spatially resolved near-infrared imaging of GN20, one of the most luminous dusty star-forming galaxies known to date, observed at an epoch when the Universe was only 1.5 Gyr old.
