Abstract
The clustering properties of faint K2.At the highest redshifts, 21.7 reach r_0~8 h^-1 Mpc comoving. This is a factor of 3--4 higher than the correlation length of LBGs with similar number densities, down to V_6061.7 colors at 2<z_phot<4 are likely older and more massive galaxies, on average, than LBGs. They were presumably formed in the highest density perturbations at early epochs. Semi-analytical hierarchical models do predict the existence of strongly clustered populations at z~3, but with at least a factor of 10 lower number density than the one measured. The overall properties of this strongly clustered population consistently suggest that they are the progenitors, or building blocks, of local massive early-type galaxies and z~1 EROs, close to their major epochs of formation.
