Title: Differentiable Astrophysics Simulations
Abstract: Reverse-mode auto-differentiable simulations offer a powerful framework for solving inverse problems, optimizing design, and conducting sensitivity analysis across scientific disciplines. In this talk we present work in progress on building a differentiable astrophysics code using JAX, supporting compressible hydrodynamics, magnetohydrodynamics (MHD), scalar fields, and self-gravity. We demonstrate its applications in solving inverse problems on some toy problems and showcase the code's scalability on distributed GPU clusters. These early findings highlight the potential of differentiable programming in accelerating scientific discovery in astrophysics through AI-driven optimization and inverse problem-solving.
