The Tully-Fisher relation and its evolution with redshift in cosmological simulations of disc galaxy formation.
PORTINARI L. and SOMMER-LARSEN J.
Abstract (from CDS):
As to evolution, we find a brightening of the TF relation between z = 0 and 1 of about 0.85 mag in rest-frame B band, with a non-evolving slope. The brightening we predict is intermediate between the (still quite discrepant) observational estimates.
This evolution is primarily a luminosity effect, while the stellar mass TF relation shows negligible evolution. The individual galaxies do gain stellar mass between z = 1 and 0, by a 50-100 per cent, but they also correspondingly increase their characteristic circular speed. As a consequence, individually they mainly evolve along the stellar mass TF relation, while the relation as such does not show any significant evolution.
