We investigate the morphological properties of 494 galaxies at z>1 from the GMASS survey, in their optical rest-frame, using HST/WFC3-IR images from CANDELS. The fractions of ellipticals and disks decline between z=1 to z=3, while at higher z the galaxy population is dominated by irregulars. Ellipticals have the highest concentration and Gini values, while irregulars assume the lowest ones. However, at 1View original:
