Disc tests

This page describes a suite of disc mass modelling tests. This constitutes four different collisionless N-body models. The files are available for download as Gadget format binary files. For information on reading/writing Gadget files, see file formats.

The units are:

  • Graph

Model Description Reference file
A An undisturbed 'Milky Way' like disc set up in equilibrium using GalactICs Garbari et al. 2011 mw_unevol.gad
B Model A evolved for 4Gyrs to form a bar and spiral arms Garbari et al. 2011 mw_evol4gyr.gad
C Model B bombarded with a low-inclination 1:10 'LLMC' like merger; evolved for XXGyrs to reach equilibrium Merger parameters as in Read et al. 2008
D Model B bombarded with a high-inclination 1:10 'LLMC' like merger; evolved for XXGyrs to reach equilibrium Merger parameters as in Read et al. 2008

In all cases, the particles are all stored in the dark matter array. The following table lists the order and number of the different particle species: DM: dark matter; disc: disc stars; bulge: bulge stars; and sat: satellite debris:

Model Particles
A Graph DM, Graph disc, Graph bulge
B Graph DM, Graph disc, Graph bulge
C Graph DM, Graph DM sat (light), Graph DM sat (heavy), Graph disc, Graph bulge, Graph star sat
D Graph DM, Graph DM sat (light), Graph DM sat (heavy), Graph disc, Graph bulge, Graph star sat
