Maps of the dark matter distribution

Maps of the dark matter distribution in the region surrounding the Aquila halo at z = 0. The dark matter is projected in cubic volumes of side length as indicated in each panel. Pixel brightness corresponds to the dark matter density using a logarithmic scale.

About

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.
