Bridging Gaseous Media Across Scales and Phases

Kim, Doyeon

The work presented in this dissertation provides the groundwork for characterizing multi-scale gaseous media, the interstellar medium (ISM) to the circumgalactic medium (CGM) in a data driven approach. Both the ISM and CGM play fundamental roles in galaxy evolution, yet their relation remains poorly understood due to the vast differences in spatial and temporal scales between them. Bridging the gap between these gaseous media at different scales requires more than observational evidence or theoretical insights in isolation. Instead, it demands a combined effort that integrates both approaches, along with the development of advanced analysis tools capable of capturing and connecting the underlying physical processes.

The results of this dissertation demonstrate the power of combining diverse observational features and probes with cutting-edge data analysis techniques. These findings enhance our understanding of structures at the interface between the ISM and CGM, and provides robust methodologies for connecting theoretical models with observations, contributing to a deeper understanding of the multi-scale gas media that impact galaxy evolution.
