Our spatially resolved data allow reliable modeling of individual galaxies, including the effect of pressure support on the inferred gravitational potential. At fixed circular velocity, we find higher baryonic masses and similar stellar masses at z∼2.3 as compared to z∼0.9. Together with the decreasing gas-to-stellar mass ratios with decreasing redshift, this implies that the contribution of dark matter to the dynamical mass on the galaxy scale increases toward lower redshift. A comparison to local relations reveals a negative evolution of the stellar and baryonic TFR zero points from z=0 to z∼0.9, no evolution of the stellar TFR zero point from z∼0.9 to z∼2.3, and a positive evolution of the baryonic TFR zero point from z∼0.9 to z∼2.3. We discuss a toy model of disk galaxy evolution to explain the observed nonmonotonic TFR evolution, taking into account the empirically motivated redshift dependencies of galactic gas fractions and the relative amount of baryons to dark matter on galaxy and halo scales. Description: This work is based on the first 3yr of observations of KMOS3D, a multiyear near-infrared (near-IR) IFS survey of more than 600 mass-selected star-forming galaxies (SFGs) at 0.6≲z≲2.6 with the K-band Multi Object Spectrograph (KMOS; Sharples+ 2013Msngr.151...21S) on the Very Large Telescope. The KMOS3D survey and data reduction are described in detail by Wisnioski et al. 2015ApJ...799..209W The results presented in this paper build on the KMOS3D sample as of 2016 January, with 536 observed galaxies. Of these, 316 are detected in, and have spatially resolved, Hα emission free from skyline contamination from which two-dimensional velocity and dispersion maps are produced. File Summary:
