Evolution of Blue E/S0 Galaxies from z ˜ 1: Merger Remnants or Disk Rebuilding Galaxies?
We define blue E/S0 galaxies as objects having a clear early-type morphology on the HST/ACS images but with a blue rest-frame color. We isolate this way 210 IAB 22 blue early-type galaxies with M* / Msun > 1010 in the COSMOS field located in three redshift bins (0.2 z 0.55, 0.55 z 0.8, 0.8 z 1.4) and study their properties (number density
