A simple JAX-powered simulation library for numerical experiments of fuzzy dark matter, stars, gas + more!

Author: [Philip Mocz (@pmocz)](https://github.com/pmocz/)

Jaxion is built for multi-GPU scalability and is fully differentiable. It is a high-performance JAX-based simulation library for modeling fuzzy dark matter alongside stars, gas, and cosmological dynamics. Being differentiable, Jaxion can seamlessly integrate with pipelines for inverse-problems, inference, optimization, and coupling to ML models.

Jaxion is the simpler companion project to differentiable astrophysics code [Adirondax](https://github.com/AdirondaxProject/adirondax)


## Install Jaxion

Install with:

```console
pip install jaxion
```

or, for GPU support, use:

```console
pip install jaxion[cuda12]
```

See the docs for more info on how to [build from source](https://jaxion.readthedocs.io/en/latest/pages/installation.html).


## Examples
