| 03/09 Thursday GM4.13 | Building astrochemical models - Open source software, surrogate models and interpretable machine learning for astrochemistry Present-day astrochemistry relies on observations, laboratory studies, theory, and computational models to understand the formation and destruction of molecules across diverse astrophysical environments. My thesis and talk focus on computational astrochemistry, specifically astrochemical models that track the abundances of molecules over time. The first part of the talk introduces our core astrochemical simulation framework, UCLCHEM (uclchem.github.io), which has been upgraded and expanded into a well-maintained, open-source code for the community. In the second part, I present a strong use case of UCLCHEM: creating and analysing templates of chemical signatures for regions in the Central Molecular Zone of our Milky Way, in support of the ACES collaboration. In the final part, I discuss modern methodology development for astrochemistry, including explainable machine learning methods for interpreting simulated molecular abundance ratios, surrogate machine learning models for accelerating three-dimensional simulations of star-forming regions, and differentiable astrochemical codes that will enable the next generation of computational studies. Together, these developments push astrochemical modelling toward faster, more interpretable, and more physically integrated simulations of the interstellar medium. | Gijs Vermariën | STRW | |
