The Aquila Project compares the results of cosmological gas-dynamical simulations of galaxy formation within a Milky Way-sized CDM halo. The various runs differ in their numerical hydrodynamical treatment but share the same initial conditions
The Aquila Project consists of 13 different gas-dynamical simulations of the formation of a galaxy in a ΛCDM halo of similar mass to that of the Milky Way. Nine different codes were used for the project (two codes were run three times each with different sub-grid physics modules). The various codes differ in their hydrodynamical technique (SPH , AMR, moving-mesh): seven codes use the SPH technique, six of which are based on gadget and one on gasoline.
