Description

Chemistry in the interstellar medium (ISM) is the crucial link between theory and observations. While hydrodynamical simulations are the standard for forward modeling, they often lack the resolution to capture essential small-scale processes. In this talk, I will demonstrate that even in cutting-edge, high-resolution simulations (on parsec scales), sub-grid clumping remains a critical missing piece. Moreover, I will discuss the limitations of the traditional clumping factors and present a novel sub-grid model that accounts for the competition between turbulent mixing and chemical reactions.
