Scientific paper

Morphology is the most accessible tracer of galaxies physical structure, but its interpretation in the framework of galaxy evolution still remains a problem. Its quantification at high redshift requires deep high angular resolution imaging, that is why space data (HST) are normally employed. At z>1, the HST visible cameras probe however the UV flux, dominated by the emission of young stars, which could bias the estimated morphologies towards late-type systems. In this paper we quantify the effects of this morphological k-correction at 11 could be underestimating the elliptical population.
