Abstract
We have used high-resolution, HST WFC3/IR, near-infrared imaging to
conduct a detailed bulge-disk decomposition of the morphologies of ~200
of the most massive (M_star > 10^11 M_solar) galaxies at 12 they are
mostly disk-dominated. Interestingly, we find that while most of the
quiescent galaxies are bulge-dominated, a significant fraction (25-40%)
of the most quiescent galaxies, have disk-dominated morphologies. Thus,
our results suggest that the physical mechanisms which quench
star-formation activity are not simply connected to those responsible
for the morphological transformation of massive galaxies.
