Description
Understanding of physical processes relevant for the evolution of the ISM is crucial for understanding of the galaxy evolution. Numerical simulations showed that several different physical mechanisms related to star formation play crucial role in the regularization and evolution of the ISM and that the same processes can also drive galactic outflows and affect the CGM. Stellar feedback via supernovae and radiation from young stars are main ingredients of successful models but several tensions with observations remain. Recently, additional physical processes such as feedback from cosmic rays started receiving more attention as a potential solution of some of these tensions. I will review the connection between the ISM physics and galactic gas flows and point out regimes where more work is needed to constrain the uncertain physical processes.
