Title:
Differentiable cosmological hydrodynamics

Abstract:
Numerical simulations are an important tool for studying the formation and evolution of structures in our universe. Increasingly, we are interested in understanding how predictions depend on parameters or specific initial conditions. These questions can be answered by codes that are auto-differentiable. DISCO-DJ is a differentiable package for cosmological simulations implemented in JAX. In a quest to extend the currently available module and to include baryon hydrodynamics, a finite volume Godunov scheme is implemented in this code. Some first results of this effort are presented here.
