Full description

We infer the intrinsic ionized gas kinematics for 383 star-forming galaxies across a range of integrated star formation rates (SFR ∈ [10-3, 102] M☉ yr-1) at z ≲ 0.1 using a consistent 3D forward-modelling technique. The total sample is a combination of galaxies from the Sydney-AAO Multiobject Integral field Spectrograph (SAMI) Galaxy survey and DYnamics of Newly Assembled Massive Objects survey. For typical low-z galaxies taken from the SAMI Galaxy Survey, we find the vertical velocity dispersion (σV,z) to be positively correlated with measures of SFR, stellar mass, H I gas mass, and rotational velocity. The greatest correlation is with SFR surface density (ΣSFR). Using the total sample, we find σV,z increases slowly as a function of integrated SFR in the range SFR ∈ [10-3, 1] M☉ yr-1 from 17 ± 3 to 24 ± 5 km s-1 followed by a steeper increase up to σV,z ∼80 km s-1 for SFR ≳ 1 M☉ yr-1. This is consistent with recent theoretical models that suggest a σV,z floor driven by star formation feedback processes with an upturn in σV,z at higher SFR driven by gravitational transport of gas through the disc.
