Abstract:
We have studied the origin of the Tully-Fisher relation by analysing hydrodynamical simulations in a ΔCDM universe. We found that smaller galaxies exhibit lower stellar masses than those predicted by the linear fit to high mass galaxies (fast rotators), consistently with observations. In this model, these trends are generated by the more efficient action of supernova feedback in the regulation of the star formation in smaller galaxies. Without introducing scale-dependent parameters, the model predicts that the Tully-Fisher relation bends at a characteristic velocity of ∼100 km s-1, in agreement with previous observational and theoretical findings. © 2011: Instituto de Astronomía.
