Abstract:
We investigate the stellar mass and baryonic mass Tully-Fisher
relations (TFRs) of massive star-forming disk galaxies at redshift
z∼2.3 and z∼0.9 as part of the KMOS3D integral field spectroscopy
survey. 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 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 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.
