Summary
. GTC spectra of 4 superdense E/S0s at z~1:
σ ~190 km/s:
Mstar ~ x6
. average age: ~1-2 Gyr
. [OII]3727 (+MIR) emission: SFR ~10-20 Mo/yr
FP, F-J and M-Re analysis consistent with a simple evolutionary scenario from z~1 to z~0:
Fading: ΔMB ~ 2.4 mag
Minor mergers: ΔM ~ x1.5, ΔRe ~ x1.8, Δσ ~ x0.8
