Description
Feedback processes play a crucial role in driving galactic outflows that shape galaxy evolution, regulate star formation, and promote the cosmic baryon cycle. Multiwavelength observations consistently reveal that these outflows are inherently multiphase. However, reconciling such observations with numerical simulations remains a major challenge due to the computational cost of capturing the complex interplay between gas phases across galactic and sub-parsec scales. In this talk, I will present a novel approach that overcomes this limitation using a multi-fluid extension of the AREPO code. This method employs a sub-grid framework to effectively track the unresolved interactions between different gas phases. I will illustrate this approach with a suite of simulations of M82-like galactic winds, addressing key questions such as (i) the structure and properties of multiphase outflows, (ii) the origin and evolution of cold gas within these outflows, and (iii) comparisons between observed and simulated multiwavelength emission lines. These findings provide critical insights into the role of multiphase outflows in driving galaxy evolution and reconciling theoretical models with observations.
