Barnes-Hut Algorithm for the simulation of a galactic disc

Autores: Ochoa J. and Narváez J. (April 2022)

Modular code in Python that implements the Barnes-Hut algorithm and a simplectic integrator for evolving a toy model of a spiral galaxy. It uses inverse transform sampling to generate random particles that follow the surface brightness distribution found in real galaxies.
