"Galaxy Kinematics from Integral Field Spectroscopy of ~1000 z~0.6-2 Star-forming Galaxies"

I will present findings from our ongoing UK KMOS GTO programme that has measured the spatially-resolved gas properties for over 1000 emission-line galaxies at z~0.6-2. Combining this sample with ~800 galaxies at z~0 from the SAMI Galaxy Survey and ~400 more at intervening redshifts (z~0.4) observed with MUSE, we are able to probe the dynamics of star-forming galaxies over an interval of ~10 Gyr. This period encompasses ~70 percent of cosmic history and includes key epochs for galaxy growth and evolution. I will highlight recent results from our programme, including a measure of the redshift evolution of the Tully-Fisher relation since z~1 and an examination of the shapes of galaxy rotation curves between z~0.6-2. I will discuss how these analyses provide insights into the processes governing galaxy evolution in our Universe.
