Scaling Relations Between Warm Galactic Outflows and Their Host Galaxies

Understand

We report on a sample of 51 nearby, star-forming galaxies observed with the Cosmic Origin Spectrograph on the Hubble Space Telescope.

• We calculate Si II kinematics and densities arising from warm gas entrained in galactic outflows.
• We use multi-wavelength ancillary data to estimate stellar masses (M$_\ast$), star-formation rates (SFR), and morphologies.
• We derive significant correlations between outflow velocity and SFR$^{\sim 0.1}$, M$_\ast^{\sim 0.1}$ and v$_\text{circ}^{\sim 1/2}$.
