Description

This program offers to calibrate intermediate scale tracers that can provide us with global understanding of star formation (SF) and galaxy evolution. These tracers are the young star clusters (YSCs). YSCs, formed by millions of stars gravitationally bound together, are fundamental units of SF. However, our understanding of their formation, interaction with the interstellar medium, and evolution is poor and contradictory. This research program will: I - quantify how global galactic physical properties modify the clustering nature of the cluster formation process and their evolution. To investigate this topic I will use two unique Hubble Space Telescope multi-wavelength datasets that homogeneously sample galaxies observed in the local Universe. II - Understand how the change in the clustering properties of SF affects, in turn, the local and global interstellar medium via stellar feedback. This study will be based on a large 3D spectroscopic campaign of the local spiral galaxy M83. This research program will reconcile our understanding of YSC formation and evolution to the foundations of SF and provide the missing connection between small and large scale processes, including stellar feedback. These results will motivate new research topics at the next-generation facilities that, with their unprecedented resolution and sensitivity, will probe smaller spatial physical scales and image further galaxies extending this investigation into a more comprehensive portion of our Universe.
