The DUVET Survey: Resolved Maps of Star Formation Driven Outflows in a Compact, Starbursting Disk Galaxy

Abstract

We study star formation driven outflows in a $z\sim 0.02$ 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, $v_{\mathrm{out}}$, from $100-600$ km s${}^{-1}$ across a range of star formation rate surface densities, ${\Sigma }_{\mathrm{SFR}}$, from $\sim$0.01-10 M${}_{\odot }$ yr${}^{-1}$ kpc${}^{-2}$ in resolution elements of a few hundred parsec. Outflows are detected in $\sim 100\%$ of all spaxels within the half-light radius, and $\sim 70\%$ 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 $v_{\mathrm{out}}$ and the ${\Sigma }_{\mathrm{SFR}}$, as well as between the mass loading factor, $\eta$, and the ${\Sigma }_{\mathrm{SFR}}$, 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 $\sim 500$ pc. Conversely, we do not find statistically significant consistency with the prediction from momentum-driven winds.
