The DUVET Survey: Resolved Maps of Star Formation Driven Outflows in a
  Compact, Starbursting Disk Galaxy
  We study star formation driven outflows in a $z\sim0.02$ starbursting disk
galaxy, IRAS08339+6517, using spatially resolved measurements from the Keck
Cosmic Web Imager (KCWI). We develop a new method incorporating a multi-step
process to determine whether an outflow should be fit in each spaxel, and then
subsequently decompose the emission line into multiple components. We detect
outflows ranging in velocity, $v_{\rm out}$, from $100-600$ km s$^{-1}$ across
a range of star formation rate surface densities, $\Sigma_{\rm SFR}$, from
$\sim$0.01-10 M$_\odot$ yr$^{-1}$ kpc$^{-2}$ in resolution elements of a few
hundred parsec. Outflows are detected in $\sim100\%$ of all spaxels within the
half-light radius, and $\sim70\%$ within $r_{90}$, suggestive of a high
covering fraction for this starbursting disk galaxy. Around $2/3$ of the total
outflowing mass originates from the star forming ring, which corresponds to
$<10\%$ of the total area of the galaxy. We find that the relationship between
$v_{\rm out}$ and the $\Sigma_{\rm SFR}$, as well as between the mass loading
factor, $\eta$, and the $\Sigma_{\rm SFR}$, are consistent with trends expected
from energy-driven feedback models. We study the resolution effects on this
relationship and find stronger correlations above a re-binned size-scale of
$\sim500$ pc. Conversely, we do not find statistically significant consistency
with the prediction from momentum-driven winds.
