A Conceptual Transport-Ancestry Framework for Fossil Galactic Structures, with Application to the Fermi Bubbles

Key Points

• This research aims to develop a framework for analyzing the transport and ancestry of galactic structures.
• Introduced a conceptual framework focusing on transport with an ancestry field.
• Examined persistent pathways that retain memory after driving forces cease.
• Applied the framework to the Fermi Bubbles as examples of fossil remnants.
• Utilized a minimal simulation approach for model predictions.
• Identified the Fermi Bubbles as potential fossil remnants of past transport phases.
• Demonstrated that memory in transport pathways influences galactic structure.
• Proposed a novel way to interpret cosmic evolution through structured frameworks.
