Modeling multi-wavelength properties of high redshift galaxies.

By comparing galaxy formation models within the ΛCDM cosmology with available data on high redshift galaxies, we show that small galaxies , with stellar masses <1011M⊙, are formed too early, are too passive since z∼3 and too old at z = 0. This is due to an overproduction of small galaxies at high redshift, visible also as an excess of ZAB∼27 V-dropouts. We discuss the consequences of this excess. [ABSTRACT FROM AUTHOR]
