AMReX-Astro is a collection of astrophysics simulation codes built around the AMReX adaptive mesh refinement library.

The main codes are:

• Castro: a compressible (magneto-,radiation-) hydrodynamics code for reactive flows.
• MAESTROeX: a low-Mach number stratified hydrodynamics code for stellar convection.
• Nyx: a cosmological n-body + hydro simulation code for modeling large scale structure in the Universe.
