Abstract:
We present the completed KMOS3D survey, an integral field
spectroscopic survey of 739 log(M*/M☉)>9 galaxies at 0.6<z<2.7
using the K-band Multi Object Spectrograph (KMOS) at the Very Large
Telescope. The KMOS3D survey provides a population-wide census of
kinematics, star formation, outflows, and nebular gas conditions both
on and off the star-forming galaxy main sequence through the spatially
resolved and integrated properties of Hα, [NII], and [SII]
emission lines. We detect Hα emission for 91% of galaxies on the
main sequence of star formation and 79% overall. The depth of the
survey has allowed us to detect galaxies with star formation rates
below 1M☉/yr, as well as to resolve 81% of detected galaxies
with ≥3 resolution elements along the kinematic major axis. The
detection fraction of Hα is a strong function of both color and
offset from the main sequence, with the detected and nondetected
samples exhibiting different spectral energy distribution shapes.
Comparison of Hα and UV+IR star formation rates reveal that dust
attenuation corrections may be underestimated by 0.5dex at the highest
masses (log(M*/M☉)>10.5). We confirm our first year results of
a high rotation-dominated fraction (monotonic velocity gradient and
vrot/σ0>3.360.5) of 77% for the full KMOS3D sample. The
rotation-dominated fraction is a function of both stellar mass and
redshift, with the strongest evolution measured over the redshift
range of the survey for galaxies with log(M*/M☉)<10.5.
Description:
Observations with the multi-IFU K-band Multi Object Spectrograph
(KMOS) at the VLT took place in Visitor Mode over 75 guaranteed time
nights between 2013 October and 2018 April (ESO periods 92-101).
The spectral resolution of KMOS (R∼3000-4000) varies for the 24
different IFUs.
