Atlas of CO Shells and IR Bubbles: Advances in Thermal ISM Physics

This work presents a comprehensive atlas of CO shells and associated infrared (IR) bubbles, highlighting their formation and characteristics as identified through intricate observational data. Utilizing Spitzer and radio SNRs, we examine the physical conditions within these shells and their impact on the interstellar medium (ISM). Key findings include detailed properties of specific CO shells, such as G015.68-0.28, and discussions on the gravitational and thermal dynamics involved in their formation. This atlas serves as a critical resource for understanding ISM processes.
