Phantom is a smoothed particle hydrodynamics and magnetohydrodynamics code focused on stellar, galactic, planetary, and high energy astrophysics. It is modular, and handles sink particles, self-gravity, two fluid and one fluid dust, ISM chemistry and cooling, physical viscosity, non-ideal MHD, and more. Its modular structure makes it easy to add new physics to the code.

Written in Python, pAGN solves AGN disk model equations. The code is highly customizable and, with the correct inputs, provides a fully evolved AGN disk model through parametric 1D curves for key disk parameters such as temperature and density. pAGN can be used to study migration torques in AGN disks, simulations of compact object formation inside gas disks, and comparisons with new, more complex models of AGN disks.
