Stellar feedback in nearby galaxies at key physical scales

Stars are a source of radiative and mechanical feedback in the ISM that is essential for the self-regulation of star formation in galaxies. Stellar feedback originates from young, massive stars, and shapes the morphology of the star forming region, but proves to be effective up to galactic-wide scales. I will present the results of my PhD work on two nearby galaxies, NGC7793 and M83, studying the star-forming regions at key spatial scales that allow us to probe the interface between the sources of feedback (stars and clusters, i.e. a few parsec scales) and their immediate surroundings (~10 pc) to kiloparsec scale dynamics. VLT/MUSE data tracing the ionised gas are complemented with HST and ALMA observations of the young stars and molecular gas, to provide a full picture of the star formation cycle.
