## Galactic Star Formation Driven Outflows

Intense star formation in galaxies results in powerful, galactic-scale outflows of gas. These outflows regulate star formation by heating or expelling gas from the galaxy, but the primary driving mechanisms are still uncertain.

I'm investigating the connection between galactic outflows and the morphology of star formation using two independent data sets covering a sample of 25 galaxies between $$1 \lt z \lt 1.5$$, with a mean mass of $$10^{10}$$ M$$_{\odot}$$ and mean star formation rate of 10.4 M$$_{\odot}$$ yr$$^{-1}$$.

The DEep Imaging Multi-Object Spectrograph (DEIMOS) on the Keck II telescope (rest-frame near-UV) provides Fe II and Mg II absorption lines, which provide constraints on the intensity and velocity of the outflows.

The Wide Field Camera 3 (WFC3) on the Hubble Space Telescope (HST) in rest-frame optical provides low spectral resolution, high spatial resolution spectroscopy yielding Hα emission line maps used to measure spatial extent and strength of star formation.

I'm in the process of comparing the outflow properties with the star formation rate and star formation rate surface density inferred from the Hα emission line maps. The combination of rest-frame UV spectroscopy and Hα mapping at high spatial resolution enables direct comparisons between star forming regions and the outflows they drive.

Future facilities such as the James Webb Space Telescope (JWST) and the upcoming Extremely Large Telescopes will extend these studies to lower masses and star formation rates, probing galactic feedback across orders of magnitude in galaxy properties.
