Description
Galactic outflows crucially transfer baryons and energy across the ISM and CGM, affecting the stellar formation history and the distribution of metals. However, the survival of cold gas in these outflows remains uncertain due to the turbulent, multiscale nature of interactions between different gas phases. In this work, we extend the current understanding of outflow dynamics by bridging simplified "cloud-crushing" simulations with more realistic models of fractal ISM morphology. We quantify how wind morphology, shaped by local ISM conditions, alters the kinematics and structure of outflows at large galactic distances. Our analysis of velocity structure functions and the multiphase nature of winds reveal important dependencies on ISM conditions and provide a new framework for understanding the gas-feeding process into galactic environments. This work suggests critical links between galactic winds and the ISM, shedding light on the intricate processes that govern the baryonic cycle and the broader context of galaxy formation and evolution.
