Pisces (or Py-ICs) is an open-source toolkit for constructing models of astrophysical systems and generating data for simulations. Designed for flexibility and ease of use, Pisces enables researchers to create a wide range of astrophysical models—including galaxies, galaxy clusters, and early universe perturbations—whether for direct analysis or as input for simulation software.
Rather than being limited to initial condition generation, Pisces provides a modular and extensible framework that supports a variety of scientific use cases. It is built to integrate seamlessly with major astrophysical simulation tools through dedicated frontends, ensuring broad compatibility and interoperability.
The core package is structured to facilitate customization and development, allowing users to adapt it to their specific research needs. All essential tools for model construction are included, with an emphasis on accessibility and ease of extension.
Development takes place on GitHub. If you encounter any issues, documentation gaps, or have feature suggestions, we encourage you to submit them via the repository's issues page.
To get started using Pisces, check out the Quickstart Guide, which provides an overview of installation, basic usage, and links to further resources. You can also explore the Full Documentation for comprehensive guides, API references, and examples.
If you use Pisces for academic work, please include a statement in your publication similar to:
Initial conditions were generated using Pisces (version), an initial conditions generator for astrophysical simulations, developed by Eliza Diggins and available at https://github.com/Pisces-Project/pisces.
