The N-Body Shop

An international collaboration of astrophysicists using and developing numerical solutions to complex, multiscale problems.

Gasoline

Gasoline is a modern SPH simulation code for astrophysical problems. It has been used for simulations of planets, stars, galaxies, and more.

ChaNGa

ChaNGa is the next generation simulation code. It uses the SPH methods and subgrid models initially developed in Gasoline and pairs them with the cutting edge Charm++ parallel programming language for extreme scalability and fault tolerance.

Analysis Tools

The N-Body shop also works to develop a wide array of analysis tools and scripts to make it easier to use simulation data to produce derived results.

Members of the N-Body Shop Collaboration

The N-Body Shop was born at the University of Washington, and has grown to include research groups across the United States, Canada, and Europe.
