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.
