Resumen:
In this work, we present preliminary results on the study of the origin and evolution of the stellar Tully-Fisher Relation (sTFR) by performing numerical hydrodynamical simulation in a cosmological frame-work. We found that the origin of the sTFR is closely related to the hierarchical growing up of the structure in the concordance cosmology paradigm in agreement with previous works. However, its evolution is strongly modulated by galactic winds, which play a fundamental role in the determination of the slope and normalization of the sTFR at different redshifts.
