In this work, we studied the stellar and baryonic Tully-Fisher relations by using hydrodynamical simulations in a cosmological framework. We found that supernova feedback plays an important role on shaping the stellar Tully-Fisher relation causing a steepening of its slope at the low-mass end, consistently with observations. The bend of the relation occurs at a characteristic velocity of approximately 100 km/s, in concordance with previous observational and theoretical findings. With respect to the baryonic Tully-Fisher relation, the model predicts a linear trend at z~0 with a weaker tendency for a bend at higher redshifts. In our simulations, this behaviour is a consequence of the more efficient action of supernova feedback at regulating the star formation process in smaller galaxies.
