(2016) for a detailed galaxy decomposi3on and a BH mass deriva3on via AO- assisted Keck/OSIRIS data. See also Emsellem et al. (2013), and Walsh et al.

17 Most early- type galaxies are fast rotators containing disks. They require a b/d/etc. decomposi3on of their light. Cappellari et al. (2013, MNRAS, 432, 1862) See also Krajnovic et al. (2013, 432, 1768) and Nic Sco\ et al. (2014, MNRAS, 441, 274). The changing face of galaxies 17

Disk growth may explain their transforma3on from z~1-2 to z=0. Abundance of z=0 compact massive spheroids (in ETGs) since confirmed by de la Rosa et al. (2016). The changing face of galaxies 19
