Scientific paper

Local and intermediate redshift (z 0.5) galaxy samples obey well correlated relations between the stellar population luminosity and maximal galaxy rotation that define the Tully-Fisher (TF) relation. Consensus is starting to be reached on the TF relation at z 0.5, but work at significantly higher redshifts is even more challenging, and has been limited by small galaxy sample sizes, the intrinsic scatter of galaxy properties, and increasing observational uncertainties. We present here the TF measurements of 41 galaxies at relatively high redshift, from the public release of spectroscopy from the DEEP2 project, observed with the Keck/DEIMOS instrument. The 'first-look' sample analyzed here has a redshift range of 0.75
