Velocity Dispersions and Stellar Populations of the Most Compact and Massive Early-type Galaxies at Redshift ~1
We present Gran-Telescopio-Canarias/OSIRIS optical spectra of four of the most compact and massive early-type galaxies (ETGs) in the Groth Strip Survey at redshift z ~ 1, with effective radii R e = 0.5-2.4 kpc and photometric stellar masses M sstarf = (1.2-4) × 1011 M sun. We find that these galaxies have velocity dispersions σ = 156-236 km s-1
