The Tully-Fisher relation and its evolution with redshift in cosmological simulations of disc galaxy formation

  title={The Tully-Fisher relation and its evolution with redshift in cosmological simulations of disc galaxy formation},
  author={Laura Portinari and Jesper Sommer-Larsen},
  journal={Monthly Notices of the Royal Astronomical Society},
We present predictions on the evolution of the Tully–Fisher (TF) relation with redshift, based on cosmological N-body/hydrodynamical simulations of disc galaxy formation and evolution. The simulations invoke star formation and stellar feedback, chemical evolution with non-instantaneous recycling, metallicity-dependent radiative cooling and effects of a metagalactic ultraviolet field, including simplified radiative transfer. At z= 0, the simulated and empirical TF relations are offset by about 0… Expand

Age-dating the Tully–Fisher relation at moderate redshift
We analyse the Tully-Fisher relation at moderate redshift from the point of view of the underlying stellar populations, by comparing optical and NIR photometry with a phenomenological model thatExpand

The baryonic Tully–Fisher relation (BTFR) is an important tool for constraining galaxy evolution models. As 21-cm H i emission studies have been largely restricted to low redshifts, the redshiftExpand
