Galactic winds are crucial for galaxy evolution. Gas that is driven above the plane of a disk in these winds naturally regulates star formation by removing itself from the available fuel to make new stars. Simulations indicate that galactic winds are the most important regulators of galaxy growth. The total mass outflow rate and the phase distribution of these winds remain, however, very poorly known due to a lack of multi-phase observations that can track mass in both warm ionised and cold gas. I will present results from the GECKOS survey. GECKOS uses very deep VLT/MUSE observations, combined with ALMA and MeerKAT observations (alongside upcoming JWST Cycle 3 observations), to study galactic winds in edge-on galaxies. Our overall aim is to create significantly sized samples of resolved, multi-phase galactic winds. The GECKOS observations allow us to identify extended filaments originating from knots of high star formation within the disk, at spatial scales of 100pc. By measuring the total mass of cold filaments (ionised gas, molecular, and atomic gas), we estimate the energy required for feedback to lift this material. We relate star formation in the disk to the energy associated with feedback. Our results can directly inform sub-grid physics for galaxy evolution simulations and serve as a benchmark for large surveys of single-phase wind measurements. Furthermore, they underscore the synergy between optical and radio observations, which will be critical in the SKA era.
