PyUltraLight v1

PyUltraLight solves the Schrödinger-Poisson in a non-expanding background and can describe the evolution of several interacting ultralight dark matter halos or one or more halos orbiting a central, fixed Newtonian potential, the latter scenario corresponding to dwarf galaxies orbiting a massive central galaxy. PyUltraLight is implemented in a Python-based Jupyter notebook which makes it simple to specify simulation parameters.

Performance-critical routines are managed via calls to computationally efficient compiled libraries with support for shared memory mutlithreading. PyUltraLight runs on standard desktop hardware and run at spatial resolutions of up to 512³ on a machine with 32GB of RAM.
