The stellar mass Tully-Fisher relation for star-forming galaxies may have looked different at z~2, results from ZFIRE and outlook with LEGA-C
The rotational velocities within galaxies are presumably tied to the angular momentum and gravitational potentials of their host dark matter haloes. At z~0 they are also tightly correlated to stellar mass, with higher velocities for more massive galaxies. This correlation is the stellar mass Tully-Fisher relation. The cosmological growth of dark matter haloes leads us to expect that the Tully-Fisher relation has evolved over time, with less stellar mass for a galaxy with a given velocity in the past. In reality, the situation is more complex as baryonic processes could have softened this evolution. Observations of the stellar mass Tully-Fisher relation at high redshift should reveal valuable insights, but unfortunately there is still considerable disagreement between current results in literature. In this talk I will present new results at z~2 from the spectroscopic survey ZFIRE and discuss various uncertainties. I will also present an exciting new spectroscopic survey: the Large Early Galaxy Astrophysics Census (LEGA-C) and how its 20-hour deep spectra of several thousand galaxies at z~0.8 will reveal new kinematic insights.
