Supernova feedback and the bend of the Tully-Fisher relation

Mostrar todas las versiones(2)

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,...
