Massive galaxies: born as disks, dead as spheroids
Abstract
Present day massive (Mstellar > 1011 M⊙) galaxies are composed mostly of early-type objects. To ascertain whether this was also the case at higher redshift, we have compiled over a thousand massive galaxies at 0 < z < 3 with HST imaging and spectroscopic redshifts for the majority of them. We have also analyzed using 3D spectroscopy another sample of 10 massive galaxies at z = 1.4. Both works highlight the progressive change between a late-type/peculiar nature at z > 2 and a predominance of early-type morphologies only since z = 1.
